ABSTRACT:
Compositions comprising polyalkylene terephthalate, polyethylene and a compatibilizer copolymer of a C.sub.2 -C.sub.10 alpha-olefin and a glycidyl or isocyanate group-containing functional compound, wherein the functional compound comprises about 0.4 to about 50 weight percent of the compatibilizer copolymer, provide improved impact properties and heat resistance. The compositions feature improved compatibility of polyalkylene terephthalate and polyethylene, and are useful in forming a wide variety of articles therefrom.
