Reactions of PVC with Organotin Stabilizers Under Controlled Conditions

Abstract

Research and development work in this area often concentrates on attempts to reproduce in the laboratory conditions which approximate to those in the actual processing equipment where degradation and stabilization occur. Such experiments are successful in evaluating and development stabilizers but are less effective in clarifying the chemistry involved. Our own work, at first with model compounds^1,2 and then with PVC itself,^3–5 has been designed to show how the polymer reacts under carefully controlled conditions so that the various reaction parameters can be isolated.
