Abstract

Compositions comprise a blend of (1) 70 to 94 weight per cent of isotactic polypropylene, (2) 1 to 25 weight per cent of an olefine polymer other than polypropylene or an ethylene/propylene copolymer and (3) 5 to 20 weight per cent of a normally solid ethylene/propylene copolymer. The olefine polymer may be a polymer or copolymer of ethylene, butene-1 and/or heptene-1. The compositions may be prepared by mixing or coprecipitation from a solvent such as isooctane or xylene, and may be moulded to form impact resistant boxes, tanks, luggage, car and refrigerator parts and battery boxes. Examples describe compositions of polypropylene, ethylene/propylene copolymers and polyethylene or polybutene-1.
