MECHANISM OF ORGANOTIN STABILIZATION OF POLY(VINYL CHLORIDE). 7. ASSOCIATION OF METHYLTIN ALKYL THIOGLYCOLATES WITH PVC AND ITS IMPLICATION IN PVC STABILIZATION

摘要

The stabilization and degradation of PVC by methyltin alkyl thioglycolates was investigated by molecular orbital calculations of the most probable reactions responsible for them. Theoretical studies confirmed previously postulated mechanisms based on experimental results.
