Preparation and properties of styrene-acrylic emulsion Research Abstract:styrene,butyl acrylate,acrylic acid as monomers,ammonium persulfate as initiator,OP-10 and SDS as the emulsifier,continuous polymerization process by dropping the preparation of styrene-acrylic emulsion.The results show that the SDS:OP-10 = 1:1 (mass ratio) composite emulsifier content of 4% of the total mass can be better prepared emulsion

Having summed up development and application of the propylene sour cube ester briefly, and the reaction mechanism and response procedure of propylene sour cube ester .Workshop regard propylene is sour and cube alcohol as raw materials to be sulphur sour to formate propylene sour man process conditions of reactor of ester as catalyst to toluene to Jilin petrochemical industry propylene sour man ester especially (Alcohol sour Mole to, ) the influence of the sour conversion ratio of propylene and impact on yield of propylene sour cube ester correctly that response temperature, response pressure, choice and consumption, response residence time of the catalyst, receive best reaction condition data, alcohol sour Mole than 1.26~1.28 at the 100% load, reaction temperature is 97.5 ℃, the first reactor pressure is 260mmHg, the second reactor pressure is 200 mmHg, what the catalyst is selected for use is sour to the sulphur of toluene, the catalyst density catalyzes 1.25% for 1.1%, always reflect residence time is 14.8 hours. Finally, according to the operational procedure of sour cube ester of propylene, want judgement and treatment of one and unusual situation after summarizing corresponding operation.
