## Abstract The presence of 2 to 3% of carbon black prevents photooxidation of polyethylene but affords only slight protection against thermal oxidation. Small quantities of amine or phenolic antioxidants are also added therefore to prevent thermal oxidation during processing. The influence of vari
A~traet--The antioxidizing effects of sterically hindered amines during thermal oxidation of low density polyethylene (LDPE) at 100 ยฐ were studied and compared with those of antioxidants of the phenolic type, by measurements of melt flow index, ultimate elongation and carbonyl index as functions of
