Abstract

1. Heat-stabilized compositions based on vinyl chloride polymers, which comprise a customary primary heat stabilizer of the type consisting of calcium-zinc stabilizing systems, and a polyhydroxylic costabilizer, characterized in that the polyhydroxylic co-stabilizer is a hyroxypropylcellulose.
