Abstract
Improvements introduced in the manufacture of copolymers, characterized in that they essentially comprise the product of the polymerization of a mixture of acrylonitrile and an unsaturated sulfonate containing at least one acrylamide radical and at least one sulfopropionamide radical linked together by a methylenic bridge, at least, the amount of said sulfonate rising to about 15% by weight of the mixture.
