Homophase synthesis of copolymers based on acrylonitrile and 2-acrylamide-2-methylpropanesulfonic acid in aqueous NaSCN solution (51.5%) with 0-25 mass% of the acidic copolymer in the monomer mixture was examined. The relative reactivities of the monomers were determined. The content of the acidic monomer in the starting reaction mixture was found to affect the integral synthesis kinetics, the monomer composition of the copolymers, and the properties of their dilute and concentrated solutions in DMF. Fibrous materials with special properties could be spun from the synthesized ionizable copolymers.

丙烯腈和2-丙烯酰胺-2-甲基丙烷磺酸共聚物的合成及性能

研究了在丙烯腈水溶液中（51.5％），丙烯酰胺和2-丙烯酰胺-2-甲基丙烷磺酸的共聚物的同相合成，其中单体混合物中有0〜25质量％的酸性共聚物。测定了单体的相对反应性。发现起始反应混合物中酸性单体的含量会影响整体合成动力学，共聚物的单体组成以及它们在DMF中的稀溶液和浓溶液的性能。可以从合成的可电离共聚物中纺出具有特殊性能的纤维材料。
