在前文研究聚乙烯醇(PVA)对丙烯酰胺聚合反应效应的基础上,本文进一步研究了PVA对N-取代丙烯酰胺衍生物聚合反应的影响。发现PVA对N-甲基丙烯酰胺的聚合反应亦有减速作用,且减速程度与添加的PVA量间有一定量关系。而PVA对N,N-二甲基丙烯酰胺的聚合反应就无此效应。为考察PVA同丙烯酰胺AM类单体间的相互作用,进行了粘度测定,并采用(化学电离)质谱的方法证实了AM及N-甲基丙烯酰胺同1,3-丙二醇间所存在的分子缔合作用。对缔合物的形或模式进行了探讨。
Based on the previous study of the effect of PVA on the polymerization of acrylamide, the effect of PVA on the polymerization of N-substituted acrylamide derivatives was further investigated. It was found that the polymerization reaction of PVA on N-methyl acrylamide also slowed down, and the degree of deceleration and the amount of added PVA have a certain amount of relationship. The PVA on the N, N-dimethyl acrylamide polymerization reaction will not have this effect. In order to investigate the interaction between PVA and acrylamide AM monomer, the viscosity was measured and the molecule existing between AM and N-methylacrylamide and 1,3-propanediol was confirmed by chemical ionization mass spectrometry Associative effect. The shape or mode of association is discussed.
