ABSTRACT:
The presence of free carboxylic acids containing from 8 to 20 carbon atoms or the anhydrides of these acids inhibits the rate of heat induced discoloration exhibited by certain polymer formulations containing as a heat stabilizer the reaction product of a carboxylic acid with a stoichiometric excess, based on the number of carboxyl groups present, of a diorganotin oxide. The free acids are virtually ineffective heat stabilizers for these polymers in the absence of the aforementioned reaction product. The polymers which can be stabilized include vinyl chloride polymers and acrylonitrile-butadiene-styrene terpolymers.
