ABSTRACT:
Disclosed are plastic grade polypropylene compositions suitable for molding and extrusion, which contain an inert particulate filler material such as talc and a polyester which greatly increases the heat stability of articles produced therefrom. The polypropylene is semi-crystalline, isotactic, having a density equal to or greater than 0.90. The polyesters used in the composition of this invention are described as linear, saturated crystalline polyesters derived at least in part from terephthalic acid and 1,6-hexanediol.
