Abstract
The process concerns stabilization of polymers against ionizing radiation where the polymer molecule contains a halogen. It comprises incorporating hydroquinone into the polymer, especially into polyvinyl chloride, the polymer containing both a metallic compound, heat stabilizer, and also a mercaptan.
