Latices of acrylate copolymer resin(ACR) with the particle size about 200 nm and relatively narrow distribution was prepared through emulsion polymerization with butyl acrylate and methyl methacrylate as monomer,1,4-butanediol dimethacrylate as crosslinker,allyloxmethyl nonylphenol ether sulfates as reactive emulsifier,and polystyrene latex as seed latex. Then,high impact polyvinyl chloride was obtained through acrylate latex in situ suspension graft copolymerization with vinyl chloride and blending. The st...
