  • Copolymers of 3-methacryloyloxy-2-hydroxypropyl trimethylammonium chloride monomer and vinyl monomer
    Patent number: 5132383
    Abstract: 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-hydroxypropyltrimethylammonium halide and 2-methacryloyloxy-3-hydroxypropyltrimethylammonium 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.
