Abstract
Vinyl halide polymers of relatively low molecular weight result when a monomer component that comprises a vinyl halide is polymerized in the presence of a free radical generating polymerization initiator and a molecular weight regulating agent that is an alkylene bis-(mercaptoalkanoate), such as ethylene bis-(mercaptoacetate).
