ABSTRACT:
A method for preparing a stable vinyl chloride based resin emulsion which comprises a copolymer colloidally dispersed in an aqueous medium, the copolymer having a Tg from 0.degree. to 50.degree. C., about 65 to 90 wt% vinyl chloride, about 5 to 35 wt% ethylene, 0 to 10 wt% olefinically unsaturated copolymerizable monomer and prepared by emulsion polymerization of vinyl chloride, ethylene and, optionally, an olefinically unsaturated comonomer in the presence of about 3 to 15 wt% polyvinyl alcohol as the dispersing agent, the polymerization method comprising
