ABSTRACT:
Polyvinyl chloride compositions with heat-deflection temperatures of above 100.degree. C are obtained by combining suspension grade polyvinyl chloride with diallyl phthalate with or without an unsaturated polyester, and appropriate polymerization catalysts for the diallyl phthalate incorporating into the polymer and polymerizable additive high loadings of ground limestone, from about 40% to about 100% of the total weight of final polymer, and conventional stabilizers for polyvinyl chloride.
