| 摘 要： | 以氧化还原引发剂和偶氮类引发剂组成复合引发体系，引发两性离子单体（DMAPS）与丙烯酰胺（AM）在盐溶液中进行自由基共聚合反应，获得了甜菜碱型两性离子共聚物P(AM-DMAPS)，采用红外光谱对共聚物进行表征。考察了总单体的质量分数、引发剂用量、引发剂各组分物质的量之比、反应温度等因素对聚合物特性黏数的影响；获得最适宜反应条件：总单体的质量分数30%，引发剂用量0.025%，反应温度20 ℃，氧化还原引发剂组分与偶氮引发剂组分的物质的量之比1∶3。在该反应条件下，可获得特性黏数高达20.2 mL/g的目标产物。

| Abstract: | Zwitterionic copolymers(P(AM-DMAPS))were synthesized by copolymerization of acrylamide(AM) and DMAPS in aqueous solutions,and the copolymerization was initiated with complex initiation system composed of redox initiator and azo initiator.The structure of the copolymers were characterized by FTIR spectroscopy.The effects of total monomer concentration,the amount of initiator,reaction temperature,and mole ratio of various components to initiator on intrinsic viscosity of copolymers were investigated.The optim... |
