摘要

P524/2385CIP Patent Application COPOLYMERS OF 3-METHACRYLOYLOXY-2-HYDROXYPROPYL TRIMETHYLAMMONIUM CHLORIDE MONOMER AND VINYL MONOMER The present invention provides a copolymer comprising the polymerization product of two or more vinyl monomers wherein one of the monomers is a mixture of 3-methacryloyloxy-2-hydroxypropyldimethyleneamine halide and 2-methacryloyloxy-3-hydroxypropyldimethyleneamine halide salt. The copolymer has an intrinsic viscosity greater than about 5 dl/g. The preferred copolymer comprises the polymerization product of acrylamide and a mixture of 3-methacryloyloxy-2-hydroxypropyltrimethylammonium chloride and 2-methacryloyloxy-3-hydroxypropyltrimethylammonium chloride. The copolymers of the present invention are particularly useful as flocculants.
