<p>Blended polymer compositions are described which comprise (A) an olefin polymer, (B) at least one second polymer having a glass transition temperature greater than the glass transition temperature of olefin polymer (A) such as: copolymers and terpolymers of styrene and maleic anhydride or a maleimide; polystyrene blended with a polyarylene ether, and optionally an elastomer; blends or reaction products of styrene-maleic anhydride or maleimide copolymers or terpolymers with elastomers; polycarbonates, etc., and (C) at least one compatibilizing agent selected from the group consisting of various block copolymers of vinyl aromatic compounds and conjugated dienes, and their partially hydrogenated derivatives. The blended polymer compositions of the present invention can be extruded, coextruded, thermoformed, blow-molded, injection-molded, compression-molded, calendered, laminated, foamed, stamped, pultruded, or extrusion die coated onto a continuous fiber to form shaped articles useful in a variety of applications. The compatibilized and blended polymer compositions of the present invention exhibit excellent heat distortion properties as well as excellent strength, toughness, stiffness, gloss, ease of processing and forming, improved filler interaction, hardness, adherability and shrinkage characteristics and they are retortable and microwaveable.</p> |
