Abstract
Procedure for the preparation of copolymers of acrylonitrile with better properties for dyeing, characterized by copolymerizing acrylonitrile with an ester of the general formula: CH2 = C (R) -R'-O-SO2-R2, in which r is hydrogen or a methyl radical, R'is a divalent hydrocarbon group and R2 is a rile group, the proportions of acrylonitrile and the cited ester being such that the copolymer contains at least 85 mol percent acrylonitrile and 0.5 to 10 mol per percent of the ester, and the copolymer thus obtained is reacted with ammonia a primary amine, a secondary amine, or a tertiary amine.
