Abstract
p-Toluensulfonic acid retards oxidation of polyethylene and, to a grea ter extent, of polyethylene-poly-p-methylstyrene blends. The real anti oxidant is p-cresol, formed by p-toluensulfonic acid transformation in oxidizing polyethylene and, in blends, through peroxidation and subse quent acid-catalyzed decomposition of hydroperoxides of poly-p-methyls tyrene.
