| 摘 要： | 研究了二硫代苯甲酸酯存在下偶氮二异丁腈引发苯乙烯(St)、St与N-对羟基苯基马来酰亚胺(HPM)、St与N-对(2-氯/溴丙酰氧基)苯基马来酰亚胺(CPPM/BPPM)的可逆加成-断裂链转移(RAFT)均/共聚,聚合物的结构由紫外-可见光(UV-Vis)与凝胶渗透色谱(GPC)表征.结果表明,St的RAFT均聚以及St与N-取代马来酰亚胺的RAFT共聚均呈现活性聚合特征,分子量随着转化率上升而增加,且分子量分布较窄.对于St的RAFT均聚,由于双基终止,聚苯乙烯(PSt)链中"戴帽效率"随着转化率上升逐渐下降.对于St与N-取代马来酰亚胺的RAFT共聚合,电荷转移复合物的形成显著地提高了共聚反应速度,并促进交替结构的形成.随后进行了以P(St-alt-BPPM)引发St的原子转移自由基聚合以制备梳型PSt,结果表明在强极性溶剂中进行的聚合过程失去可控性,所得产物分子量极宽,而在本体聚合中所得聚合物分子量相对较窄,有一定的可控性.

| Abstract: | The RAFT homopolymerization of St and copolymerization of St with N-substituted maleimides such as HPM,CPPM and BPPM,using AIBN as initiator,1-phenylethyl dithiobenzoate or cumyl dithiobenzoate as the chain transfer agent was investigated.The polymers were characterized by UV-Vis and GPC.The results suggested that both the homopolymerization and copolymerization exhibited a living behavior,and the molecular weight increased with the conversion and a narrow molecular weight distribution was achieved.For the ... |
