Stabilization of polyolefins against degradative deterioration as a result of exposure to light and air at elevated temperatures

摘要

Stabilizer mixtures that are capable of enhancing the resistance of polyolefins to degradation as a result of exposure to light and air, particularly at elevated temperatures, are obtained by reacting an alpha -olefin with an ester of a mercaptocarboxylic acid and a polyhydric alcohol, forming a reaction product of unknown structure containing thioether groups and carboxylic acid ester groups.
