| 摘 要： | 采用马来酸酐(MAH)作为聚苯乙烯阴离子活性链(PSLi)的封端剂,合成出末端含甲酰基丙烯酸结构的大分子单体,并通过凝胶渗透色谱,红外及拉曼光谱对末端官能团进行表征,根据反应动力学推测出PSLi与MAH的封端反应主要按SN2双分子亲核取代反应机理进行.同时还得到了温度、时间和MAH/PSLi摩尔比等反应条件对封端效率的...

| Abstract: | Polymers bearing a single formoxyl acrylic group at the chain end were synthesized by reacting between poly(styryl)lithium and maleic anhydride(MAH).The functionalized polymer was characterized by GPC,IR and Raman.The end-capping mechanism was figured,including the possible coupling reaction of dimmer.According to kinetic study,the reaction behavior could be explained by SN2 mechanism.Specifically,various factors related to functionalized efficiency,such as temperature,time of end-capping reaction,MAH/PSLi ... |
