N-乙烯基甲酰胺与乙烯基环己酰胺的共聚反应

Copolymerization of N-vinylformamid and N-vinylcaprolactam

N-乙烯基甲酰胺(NVF)是丙烯酰胺(AM)的同分异构体,用N-乙烯基甲酰胺聚合物代替聚丙烯酰胺及其共聚物,可减少二次环境污染.用N-乙烯基甲酰胺与丙烯酰胺进行不同摩尔配比的共聚反应,然后用乙烯基环己酰胺(NVCA)代替丙烯酰胺与N-乙烯基甲酰胺继续进行不同摩尔配比的共聚反应,观察不同单体,不同摩尔配比的共聚反应过程.对共聚产物进行元素分析和红外光谱分析,测定了相应共聚物的玻璃化转变温度.

N-vinylformamid is isomer of acrylamide. The latter can be used to replace copolymerization of N-vinylformamid and its copolymer, reducing second environmental pollution. In different molar ratio＇ s condition, N-vinylfomaamid and acrylamide can carry out copolymerization before the copolymerization of N-vinylcaprolactam and N-vinylformamid continue. A study of the different monomers and different molar ratio＇s process of copolymerization is conducted. The copolymer compositions are analyzed and the glass transition temperatures of copolymer are determined.
