Abstract
An improved bulk polymerization of vinyl halide is disclosed wherein reactor scale formation is substantially reduced by polymerizing in a single or two stage bulk process a vinyl halide monomer containing up to 50% of a comonomer in contact with a combination of a polyolefin, water, and an inert fine particle size additive which is a solid at the reaction temperature, or water and said additive, optionally in the presence of a surface active agent. Compositions produced by the process of the invention are useful in making films, coated fabrics and molded objects.
