Abstract

A blend comprises polypropylene (in 20 to 90% by weight) and a random ethylene-propylene copolymer containing not more than 10% by weight of ethylene, both polymers being at least 90% by weight insoluble in boiling diethyl ether. The blend may have its melt index raised by thermal degradation and may comprise unspecified stabilizers.
