摘要
通过苯乙烯与少量的甲基丙烯酸、马来酸酐或4—乙烯基吡啶的共聚及甲基丙烯酸正丁酯与马来酸酐的共聚,可在聚苯乙烯及聚甲基丙烯酸丁酯链上分别引入功能基因羧基、酸酐基和吡啶基对共聚物进行了红外光谱、酸碱滴定、元素分析、玻璃化转变温度、粘度及紫外光谱的测定.结果表明,通过在聚合物分子链上引入功能基因,可以大大增加分子链内或链间作用力,从而导致了聚合物的玻璃化转变温度的升高。
hrough copolymerization of styrene with few quantity of methacrylic acid, maleic anhydrate or 4-vinyl pyridine respectively and of butyl methacrylate with maleic anhydrate, the functional groups carboxyl, simple anhydride and pyridyl have been introduced respectively to the chain of PS or PBma. The polymers have been detected with IR,acid-base titration, element analysis, glass transition temperature,Viscometry and UV. The results show that introducing functional groups to the chain of polymer molecule will strengthen their apparently the interaction force of inter-and intra-molecular chain, rising its glass transition temperature, causing an abnormal high viscosity and making its UV absorption peak widened.
