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％ZnCl_2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。
1. The reactivity ratios of acrylamide and acrylonitrile in several concentrated inorganic salt solutions, in various concentrations of NaSCN and 4.8% KCl were measured and the results were similar to each other. The reactivity ratio of acrylonitrile and methyl acrylate in 52% NaSCN, 64% ZnCl 2 was determined. 3. The copolymerization of these two monomers in 52% NaSCN at different conversion rates basically complies with the results calculated by Skeist’s formula.
