ABSTRACT:
Vinyl halide homopolymers, copolymers and graft polymers of substantially lower molecular weight are obtained when polymerization is carried out in the presence of an organotin mercaptide ester and an organic azo initiator. The products are faster fusing and have lower melt viscosities than corresponding polymers of the same molecular weight prepared by high temperature molecular weight reduction methods. The low molecular weight and excellent fusion characteristics of the products render these polymers particularly useful in molding, extrusion, and coating applications.
