ABSTRACT:
A high bulk density/low porosity polyvinyl chloride resin which is highly processable and thermally stable is prepared by suspension polymerization wherein a vinyl chloride monomer is polymerized in the presence of: hydroxyethyl cellulose; an internal lubricant-type long chain compound such as butyl stearate; and a water insoluble/monomer soluble initiator such as lauryl peroxide, and wherein the polymerization is performed under low shear conditions in the presence of a minimum amount of oxygen.
