ABSTRACT:
Filled polymer compositions based on polypropylene block copolymer, particularly medium and medium to high impact grades, and a plate like filler such as talc, have improved visual scratch resistance by the inclusion of a polyorganosiloxane, particularly a polyalkylsiloxane such as polydimethylsiloxane. Silicone oils having viscosities of about 30,000 cSt are especially useful. Further benefits are obtained by the further inclusion of a fatty acid amide and/or by the use of passivated filler, particularly by the inclusion of an epoxy resin.
