Synthesis and Properties of Copolymers Based on Acrylonitrile and 2-Acrylamide-2-Methylpropanesulfonic Acid

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.
