ABSTRACT:
A vinyl chloride polymer formulation having a chlorinated olefin polymer as an impact modifier, and an oxidized high density polyethylene homopolymer having an acid number of from about 5 to about 40 as a fusion promoter can be converted into shaped articles. The invention includes an improved olefin polymer impact modifier composition for use with vinyl chloride polymer formulations, the composition comprising a combination of said chlorinated olefin polymer and said oxidized high density polyethylene homopolymer. The vinyl chloride polymer formulation of the present invention is useful, for example, as a feedstock for the preparation of shaped articles such as vinyl siding and vinyl window frames.
