ABSTRACT:
A compatibilized polymer alloy has been developed which has excellent processability under thermoforming conditions and the molded articles produced from the alloy exhibit superior gloss, shrinkage, surface hardness, polarity, strength and high heat distortion. The alloy is, in general, comprised of a polyolefin composition, a polystyrene copolymer, or polymer blend, and a compatibilizing agent. This polymer composition or alloy is particularly useful in producing packaging materials and food containers.
