甲基丙烯酸甲酯-苯乙烯-马来酸酐三元共聚物的本体转移悬浮聚合法

摘要

The radical shift in situ suspension polymerization of styrene（ST）-methyl methacrylate（MMA）-maleic anhydride（MAH） copolymer.The polymerization have the advantages of bulk polymerization and suspension polymerization,protecting the maleic anhydride of easy hydrolysis,prepared a high content of anhydride of copolymer,the effect of the initiator,the dispersant and the prepolymer conversionon on the reaction was studied,the relationship of the ratio of monomers between the property product%本研究采用本体转移悬浮聚合法合成苯乙烯（ST）-甲基丙烯酸甲酯（MMA）-马来酸酐（MAH）三元共聚物。本聚合法结合了本体聚合和悬浮聚合的优点,通过本体预聚降低马来酸酐水解程度,制备了高酸酐含量的三元共聚产物,研究了引发剂、分散剂用量和预聚转化率对反应的影响,并比较不同单体比例与最终产物的性能关系。
