大单体引发剂引发丙烯酰胺与二甲基二烯丙基氯化胺共聚物的合成

8 Synthesis of Copolymerization(Acrylamide-Dimethyl Dially Ammonium Chloride) Initiated by Macromer Initiator

利用丙烯酰胺和二甲基二烯丙基氯化胺共聚制得阳离子聚电解质。实验结果表明,在该聚合体系 中大单体引发体系是两单体共聚优秀引发剂;该聚合体系的最佳条件是:单体浓度18％,引发剂用量为 单体质量的1.6％,AM与DMC的摩尔配比为8:2.聚合温度30℃。

High instrisic viscosity copolymer of AM-DMC is sythesised by macromer initiator PAA/(NH4)2S2O8. The experimental results show that the macromer initiator is the best of three initiators. Further more, the effects of concentration, the ratio of AM, DMC,quanity of initiator on intrinsic viscosity and conversion are studied.
