Abstract
The heat and light stability imparted to vinyl halide polymers by metal compounds conventionally employed for this purpose is considerably improved by the presence of a mercapto ester such as 2-mercaptoethyl stearate. The esters can replace a substantial portion of the metal compound with no significant reduction in stability.
