Pyrolysis of polymers in the presence of a commercial clay
Pyrolysis of polymers in the presence of a commercial clay
The catalytic effect of a commercial sepiolite in the pyrolysis of PE, PP, PS and EVA has been studied. The results obtained show
that, despite the low ‘‘nominal’’ catalytic activity of this clay, it has enough catalytic properties to produce a marked decrease of the
temperature of decomposition of PE and PP. However, the steric effects related to the substituents of PS and EVA cancels this
catalytic behaviour. Experiments performed in an oxidizing atmosphere showed that the process is much more complex and involves
more decomposition steps, but no noticeable decrease in the temperature of any process may be related to the presence of the clay.
Nonetheless, the yield of carbonous residue is higher in the presence of the sepiolite.

that it is well known that the surfaces of CFs can be
modified by surface treatments.The majority of such
efforts were concentrated on increasing fibre–matrix
adhesion through the use of surface treatments.7,8
In this study,the authors aimed to produce SCF
reinforced ABS materials by twin screw extrusion to
observe the effects of the fibre surface modification
effect on the mechanical and morphological properties
of injection moulded composites.The authors also
focused on the effects of incorporating polar groups by
blending ABS with polyamide 6 (PA6) to functionalise

to observe the effects of improved interfacial adhesion
between the fibres and the polymer matrix.

英语翻译
In this study,the monolithic polymers were prepared by thermal-induced polymerization which was similar to the initial efforts of Puoci et al.The bulk polymers developed herein had the following notable differences with the previous report:higher cross-linking density and more polar porogenic solvent.Comparison in the binding performance of the polymers prepared in this study and that reported previously,has an imprinting effect of 2 for the former,while for the latter no imprinting effect was observed for thermal-induced polymerization and imprinting effect of 1.47 was observed for photo-induced polymerization of the imprinted polymers in relation to the non-imprinted polymers as demonstrated in this paper.Discrepancies in the binding performances of the MIPs reported in this study and that previously reported could be attributed to differences in the degree of cross-linking density as the molar ratio of template:monomer:cross-linker used in this study was 0.5:8:50 whereas the previously reported ratio was in the range of 1:8:25 to 1:16:25.Such variation in the cross-linking density may give rise to different degree of rigidity of the polymers suggesting that polymers with more rigidity would exert better binding performance.Another possible explanation for the higher imprinting effect of polymers described in this paper may also be attributed to differences in the chemical properties of the porogenic solvents used in this study and that previously reported.In this regard,the polymers described herein were prepared indichloromethane (dielectric constant of 8.93) while those previous reported were made in chloroform (dielectric constant of 4.8069).On the basis of the dielectric constant,dichloromethane is clearly a more polar solvent than chloroform,which is also more favorable for subsequent rebinding in the polar binary mixture of ethanol (dielectric constantof 25.3) and water (dielectric constant of 80.1).An added benefit of the use of more polar porogenic solvent is that it helps reduce the polarity gap of solvent used for polymer preparation and solvent used for rebinding experiments.Such reduction in the polarity gap helps reduce the degree of polymer swelling,which may perturb the binding cavity and adversely affect the binding performance.

与波西•F等人最初的研究成果相似,这次试验中获得的单片聚合物也是通过热聚合的方法制取的.此次制取的大部分聚合物与此前公布的制取出的聚合物相比,明显有很大不同.差异如下:此次试验制取的聚合物交联密度更高,致孔溶剂也更多;对比两次制取的聚合物的性能也可以发现,此次研制的聚合物中,其中两种都有印记效应,而此前公布的制取的聚合物对热聚合没有印记效应;此次试验的研究报告还指出,将印迹聚合物与非印迹聚合物作以对比,可以发现光致聚合物对印迹聚合物的印记效应已达到了1.47.

这次研究报告中的分子聚合物的结核性能与此前研究中制取的聚合物结核性能也存在较大差异,者有可能是交联密度方面存在差异而造成的.因为此次试验所用的模板分子,单体以及交联剂的比例为0.5:8:50;而之前试验所用的此三种物质比例则在1:8:25到1:16:25之间变化.若交联密度的不同可能会造成聚合物刚性的不同,则意味着高刚性聚合物的结核性能更为良好.

关于这次实验报告中出现高印迹聚合物,另一个可能的解释是因为此次研究中所用致孔溶剂的化学性能与此前研究中所用的致孔溶剂的化学性能不同.从这个方面说,此次试验制取的聚合物是在二氯甲烷(电介常数为8.93)中指出的,而此前制取的聚合物是从三氯甲烷(介电常数为4.8069)中制取的.在介电常数不同的基础上,很明显二氯甲烷溶剂比三氯甲烷溶剂的极性更强,在乙醇(介电常数为25.3)和水(介电常数为80.1)这些极性二元混合物中也更有利于进行后续重组.

使用高极性致孔溶剂的另一个好处就是,当溶剂被应用于制取聚合物和溶剂重组试验时,高极性致孔溶剂可以减少这之间的极性差距,极性差距的缩小,又有助于减小聚合物的溶胀程度.而聚合物过大的溶胀程度,则会扰乱结合腔的结合,并对结核性能造成不利的影响.

英语翻译
Extrusion
In the extrusion process,polymer is propelled continuously along a screw through region of high temperature where it is melted and compacted,and finally forced through a die shaped to give the final object.
Extrusion is used to make three main types of products:
1 Standard profile such as rod,pipe,sheet,and irregular cross sections.
2 Extrusion around wire and cable as a protective coating.
3 Film to be used along and as coatings for paper,cloth,and other surfaces.
Each of these types can be made in varying sizes depending upon the size of the machine.Extruders are designated as to size by the diameter of the rotating screw.They range from large industrial extruders with screw diameters up to 6 in or 8 in,down to the laboratory model with a 3/4 in diameter screw.Extrusion is used only for the processing of thermoplastic resins.
The screw of an extruder is divided into several sections,each with a specific purpose (Chung 1977 ).The feed section picks up the finely divided polymer from a hopper and propels it into the main part of the extruder.In the compression section,the loosely packed feed is compacted,melted,and formed into a continuous stream of molten plastic.Some external heat must be applied,but much is generated by friction.The metering section contributes to uniform flow rate ,required to produce uniform dimensions in the finished product,and builds up sufficient pressure in the polymer melt to force the plastic through the rest of the extruder and out of the die.Since viscous polymer melts can be mixed only by the application of shearing forces (their viscosity is too high to allow turbulence or diffusion of contribute appreciably to mixing),an additional working section may be needed before the die.

英语翻译
The term macromolecule,or polymer,is applied to substances of high molecular weight that are composed of a large number (usually at least 100) of units of low molecular weight joined by covalent bonds.If the low molecular weight units making up the macromolecule are bonded end-to-end in a long chain and no covalent chemical bonds exist between the chains,the macromolecules are called linear polymers.Such polymers.Unless of extremely high molecular weight (1000000),can usually be dissolved and ,when heated,they soften or melt so that they can be extruded into fibers or molded into desired shapes.These polymers are said to be thermoplastic.On the other hand,if the polymer chains are linked together at numerous points,the polymer is one large three-dimensional molecule,infusible and insoluble.Such polymers are called cross-linked polymers,and the bonds connecting the chains are cross-links.Certain linear polymers,referred to as thermosetting,contain groups which ,when heated,react to give cross-linked polymers.
The process by which small molecules undergo multiple combination to form macromolecules is polymerization.Small molecules from which a macromolecule or polymer can be made are called monomers.Two types of polymerization are recognized :(1)condensation polymerization and (2)addition polymerization.A polymer-forming reaction involving elimination of a small molecule such as water or alcohol between monomer units is described as condensation polymerization.In addition polymerization,unsaturated or cyclic molecules add to each other without elimination of any portion of monomer molecule.The empirical formula of the polymer is then,of course,the same as that of the monomer.
Reactions capable of forming macromolecules by either addition or condensation polymerization must be functionally capable of proceeding indefinitely.Whenever two monomer molecules react,the product must contain a functional group capable of reacting with another molecule of monomer.In condensation polymerization,the monomer need have only one functional group -the presence of two or more functional groups usually leads to the production of cross-linked addition polymers.

所谓高分子或聚合物,是指由大量的轻量分子单位(通常最少有100)通过共价键连接一起组成高重量分子的物质.如果组成高分子的轻量分子单位是头尾连接成为一条长链,而链与链之间没有共价化学键,这种高分子被称作线性聚合物.除非属于特高的分子重量,这种聚合物通常可以被溶解,而当被加热时会变软或融化,因此可以挤压成纤维或模塑成需要的形状.这些聚合物叫做热塑性塑料.在另一方面,如果这些聚合物链条在多个点位连接在一起,这聚合物变成一个大型三维分子,不熔化也不溶解;这种聚合物称为交联聚合物,因为连接这些链条的键是交联的.一些被称为热硬化性的线性聚合物,其所含有的分子组当加热后,会反应生成交联聚合物.小分子经过多层次组合而形成高分子的过程叫做聚合反应.能够形成高分子或聚合物的小分子称为单体.公认的两种聚合反应是:(一)冷凝聚合反应及(二)加成聚合反应.单体分子之间涉及消除小分子如水或乙醇的聚合反应叫做冷凝聚合反应.在加成聚合反应中,非饱和或循环分子相互添加但不消除单体分子的任何部分.聚合物的实验公式当然是与单体相同的.
能以冷凝聚合或加成聚合生成高分子的反应,必须在机能上能够无限进行下去.每当两个单体分子产生反应,其产生物必须含有能与另外单体分子产生反应的功能组.在冷凝聚合反应中,单体仅需一个功能组,如果存在两个或以上,通常会导致交联加成聚合物的产生.

英语翻译
The phenomena of interpolymer interactions have been the focus of intensive fundamental and applied research on polyelectrolyte complexes (PECs).The PECs prepared from natural polymers such as proteins and polysaccharides have the additional advantage ofbeing non-toxic and bioabsorbable.Protein polyelectrolyte interactions have been concerned widely with biotechnological and biomedical applications such as protein purification,enzyme immobilization,immunosensing and bioactive sensors.Several globular proteins and polyelectrolytes (natural or synthetic) have been matched for various techniques and objectives of investigation.Table l represents some examples of researches on the formation of protein/polysaccharide systems in literature.

共聚物相互作用的现象已成为聚电解质复合物(PECs)的基础研究和应用深入研究的重点.由蛋白质和多糖等天然聚合物制备的聚电解质复合物具有无毒、生物可吸收性的额外优势.蛋白质类聚电解质的相互作用在生物技术和生物医学传感器的应用方面得到了广泛的关注,如蛋白质的纯化,酶的固定,酶联免疫传感和生物活性传感器.一些球状蛋白质和聚电解质(天然的或合成的)已经被匹配结合以用作各种技术手段和研究对象.表1呈现了一些文献中对蛋白质/多糖系统的结构进行研究的例子.
楼上的一些关键词没翻好……不过我也不是很专业,有不对的地方还请大神指教.
interpolymer:共聚物
immunosensing:酶联免疫传感

应该是它们有相同的结构。比如蛋白质有肽键 脂肪是酯键,而我不知道尼龙和涤纶分别有什么键~

尼龙,有-CO-NH-键.(类似蛋白质的高聚物),但尼龙不是a-氨基酸脱水缩合成的,而是别的氨基酸.所以也有的地方说尼龙是肽链聚合物.而涤纶是酯聚合物.这下你知道了吧,尼龙和蛋白质一样,而涤纶应该与脂肪一样
请问这个化学结构式表示的物质是什么?不好意思,忘了提一句:polymer是表示聚合物海藻酸钠

化学高分子只是一种分子结构中小单元的组合,一般情况下分子式固定,分子空间结构一般不影响其化学性质.
蛋白质不但有复杂的组合方式,也有异常复杂的空间结构,任何空间结构上的差异都会使蛋白质有着本质的差别
