Abstract

Abstract: Atom transfer radical polymerization (ATRP) of acrylamide was carried out in aqueous solution at 50 ℃ using water soluble initiator 2-chloropropionamide and CuCl/CuCl2/tris(2-dimethyl/aminoethyl)amine (Me6TREN) as the catalytic system. The results show that the polymerization can reach higher conversion (86%). Furthermore, the molecular weight increases with increment of the conversion, and the molecular weight polydispersity index (PDI) of the polymers is low (about 1.10). Finally, the living character of the polymerization is confirmed by chain-extension experiments. 

摘要： 在水介质中, 反应温度50 ℃, 以水溶性引发剂2-氯丙酰胺为引发剂, 以氯化亚铜/ 氯化铜/ 三-(N , N-二甲氨基乙基)胺(Me6 TREN)为催化体系, 实现丙烯酰胺的原子转移自由基聚合(ATRP)。结果表明, 聚合转化率达到86 %;相对分子质量随转化率增大而增大, 且聚合物相对分子质量分布(PDI)较低(1 .10 左右)。最后由链增长实验证明聚合活性。
