Abstract

A process is disclosed for making polyfunctional N-chloramide derivatives of homo--or copolymers of acrylamide or metharylamide wherein a homo--or copolymer of acrylamide or methacrylamide is chlorinated by means of chloride in a dilute aqueous suspension of a mineral acid at a temperature of 0.degree. to 40.degree.
