摘要

1.测定了丙烯酰胺和丙烯腈在几种浓无机盐溶液中

各种不同浓度NaSCN中

以及4.8％KCl中的竞聚率

所得结果彼此相近。 2.测定了丙烯腈和丙烯酸甲酯在52％NaSCN

64％ZnCl2中的竞聚率。 3.此两组单体在52％NaSCN中共聚合时

在不同转化率下的共聚物组成基本上符合按 Skeist 公式所计算的结果。

Abstract

Copolymerization of acrylonitrile (AN) with acrylamide (AAm) in concentrated aqueous solutions of inorganic salts，such as 52％ NaSCN，60％ ZnCl2，34％ Mg (ClO4)2， and in various concentrations of aqueous solution of NaSCN at 60±0.1℃．initiated by azo-bis-isobutyronitrile，has been studied．It has been found that the monomer reactivity ratios of the monomer pair in various concentrations of inorganic salt solutions are almost similar to one another and also similar to the result obtained from the copolymerization carried out in water medium as reported by Reicherr．Copolymerization of Acrylonitrile with methyl acrylate (MA) in 52％ NaSCN and 64％ ZnCl2 has been also studied．Results show that the composition of AN-AAm，AN-MA Copolymers at any degree of oolymerization conversion is approximately in agreement with the results calculated from the Skeist equation．
