烯烃聚合物的制备

以可再生大豆油为原料，通过醇解、环氧化、丙烯酸酯化等一系列化学反应制备丙烯酸长链烷基酯，再用共聚单体苯乙烯与丙烯酸长链烷基酯在一定条件下进行共聚，合成含长链烷基支链的苯乙烯/丙烯酸酯共聚物.并研究了反应温度、原料用量、反应时间等因素对醇解反应、环氧化反应的影响.通过红外光谱法对合成各阶段产物结构进行表征，鉴定产物的结构.结果表明，合成的聚合物不但可以生物降解，降解后产生的小分子还可参加生物代谢循环并且被同化吸收，从而可以克服原始石油基聚合物因废弃后不能生物降解所造成的环境污染问题.

Preparation of alkene polymer

The long chain alky acrylate was fabricated using recycled soybean oil as raw material through a series of chemical reactions such as alcoholization,epoxydation,acrylic esterification.This long chain alky acrylate was then used to prepare the styrene copolymer.The effect of reaction temperature,material dosage and reaction time on alcoholization and epoxydation reactions were studied.The structure of the reaction products was identified by IR.The result shows that comparing with the traditional petroleum-ba...
