Cellular vinyl chloride polymers |
| abstract |
Abstract of the Disclosure - Cellular vinyl chloride polymers are prepared in the presence of a blowing agent and a diorganotin dimercaptide such as di-n-butyltin bis(dodecyl mercaptide). These organotin compounds are unique in that they activate the blowing agent to achieve maximum gas evolution at conventional processing temperatures while imparting a superior level of heat stability to the polymer. The dimercaptide is preferably employed in combination with a specified organotin derivative of a carboxylic acid, alcohol or phenol and/or metal salts of carboxylic acids containing between 4 and 18 carbon atoms wherein the metal is selected from Group IIB of the Periodic Table. -i- |
