ABSTRACT:
Improvement in the weathering properties of polyolefin resins has been achieved by intimate compositions comprising Ziegler-process crystalline polyolefins containing halogen-magnesium compounds as catalytic carrier residues, and organic phosphorus compounds such as organic phosphites. The compositions may contain auxiliary components normally used in polyolefin resins; antioxidants and/or ultraviolet absorbers are especially useful.
