Abstract
A thermoformable polymer blend composition comprising at least 50% by weight of an olefin polymer such as polyethylene or polypropylene, from 10 to 48% by weight of a styrene polymer and from 2 to 40% by weight of a thermoplastic styrenic block copolymer rubber, preferably a styrene-butadiene-styrene block copolymer, which acts as a compatibilizer for the olefin and styrene polymers in the blend. This blend can be formed on conventional machinery to give products having the beneficial properties of both types of polymers.
