Abstract

Abstract Investigations were made on the effects of alkyl (aryl) tin salts of maleic and thioglycolic acids and their esters upon the rate of dehydrochlorination and crosslinking, and on the absorption spectrum of PVC during degradation in vacuum at 190. It was shown that these stabilizers cause dehydrochlorination of PVC to be eight times less than the rate of polymer degradation in vacuo with removal of HC1. The stabilizers are arranged ...
