Primary Pyrolysis Products of Thiokol Liquid Polysulfide

Abstract

An analysis of the primary degradation products of the widely used commercial polysulfide polymer Thiokol LP-33 by direct pyrolysis−mass spectrometry (DP−MS) is reported. The mechanism of degradation is through a radical process involving the random cleavage of a formal C−O bond followed by backbiting to form the cyclic products.
