Abstract
The heat stability imparted to vinyl polymers by a given concentration of certain sulfur-containing organotin compounds is not adversely affected with respect to either long term stability or delay in appearance of initial discoloration when a portion of the sulfur-containing organotin compound is replaced by certain less effective organotin stabilizers, including tetraorganotin compounds and diorganotin carboxylates.
