摘要： The reaction cycle time for the copolymerisation of unsaturated esters such as alkyl fumarates and vinyl acetate, and for the polymerisation of methacrylates and acrylates may be dramatically reduced by carrying out the polymerisation at elevated temperatures and pressures. An additional feature is the addition of initiator during polymerisation which leads to improved products especially for lubricating oil pour depressants and fuel and crude oil flow improvers.

摘要翻译： 通过在升高的温度和压力下进行聚合，可以显着降低不饱和酯如富马酸烷基酯和乙酸乙烯酯的共聚反应循环时间和甲基丙烯酸酯和丙烯酸酯的聚合反应循环时间。 另外的特征是在聚合期间添加引发剂，这导致改进的产物，特别是对于润滑油倾倒抑制剂和燃料和原油流动改进剂。
