Patent

CA 2137901

Quaternary copolymers of A) from 20 to 99% by weight of one or more N-vinyllactams, B) from 1 to 80% by weight of one or more dialkylaminoalkyl acrylates or methacrylates, based on the quaternized form, and C) from 0 to 50% by weight of one or more monomers capable of undergoing free radical copolymerization. are prepared by first quaternizing the monomers B with an alky- lating agent and then subjecting the quaternized monomers B to free radical copolymerization with the monomers A and C.
