Abstract: High molecular weight cationic copolymers of (meth)acrylamide and tertiary or quaternary aminoalkyl(meth)acrylates are produced by copolymerization of said monomers in the presence of a redox system of a water-soluble percompound and of a compound containing at least one primary amine group or a water-soluble salt thereof in aqueous oxygen-free solution at a temperature of from 10* to 40*C.
