ABSTRACT:
A stabilized polyethylene composition containing catalyst residues comprising at least one transition metal comprises (a) polyethylene, (b) 100 to 2000 ppm by weight based on the total weight of the composition of one or more antioxidants of the phenolic type and (c) 100 to less than 2000 ppm by weight, based on the total weight of the composition of zinc oxide but substantially no calcium stearate. The composition has improved color and improved resistance to coloration effects.
