摘要

Preparing a vinyl chloride-graft copolymer resin comprises: (a) mixing an acrylic copolymer latex, vinyl chloride monomers, a coagulation agent and deionized water; and (b) adding methylcellulose and hydroxypropyl methyl cellulose as dispersion agents and a polymerization initiator to the mixture obtained from the step (a) before polymerization temperature of the acrylic copolymer and vinyl chloride monomer is reached, followed by graft polymerization.
