ABSTRACT:
Vinyl halide polymers of relatively low molecular weight are obtained when a monomer component comprising a vinyl halide is polymerized in the presence of a free radical generating polymerization initiator and a molecular weight regulating agent that is a polybromobutene, such as 1,1,2,4-tetrabromobutene-2. The products have low melt viscosity and excellent fusion characteristics that make them valuable in molding, extrusion, and coating applications.
