ABSTRACT:
Vinyl halide homopolymers, copolymers and graft polymers of substantially lower molecular weight are obtained when polymerization is carried out in bulk in the presence of a small concentration in the polymerization reaction mass of an aldehyde which is devoid of ethylenic and acetylenic unsaturation and which contains at least one carbon to carbon bond. The polymers are obtained without substantial lowering of the polymerization conversion rate and are characterized by excellent fusion properties and improved solubility in organic solvents, which properties render the products useful in molding, extrusion, coating and solution casting applications.
