ABSTRACT:
The density of rigid foamed articles made by the thermal decomposition of a blowing agent in a vinyl chloride polymer is reduced by the use of an organotin mercaptoalkylcarboxylate, alone, or in combination with an organotin halide or carboxylate which activate the blowing agent. Sulfides made from said organotin mercaptoalkylcarboxylate are also superior activators of the blowing agent.
