本文对铈离子与苯基氨基甲酸酯类化合物在H_2O-CH_3CN(3∶1,V/V)及H_2O-HCONH_2(1∶2,V/V)两种介质中引发丙烯酰胺的聚合进行了研究。考察了不同结构的苯基氨基甲酸酯对聚合的影响。苯基氨基甲酸酯类化合物对铈离子引发聚合均有促进作用,其中对-甲苯基氨基甲酸酯的促进作用最为显著。测定了聚合反应表现活化能及聚合动力学方程,并提出了聚合反应机理。 In this paper, the polymerization of acrylamide induced by cerium ions and phenylcarbamates in two media of H_2O-CH_3CN (3:1, V / V) and H_2O-HCONH_2 (1: 2, V / V) . The effects of different structures of phenyl carbamates on the polymerization were investigated. Phenylcarbamates promoted the initiation of cerium ion-initiated polymerization, and the promotion of p-tolylcarbamate was the most significant. The activation energy and kinetic equation of polymerization were measured and the mechanism of polymerization reaction was proposed.
