ABSTRACT OF THE DISCLOSURE A process for the preparation of moldable polymer blends having improved low temperature impact properties and reduced brittleness is disclosed. In one embodiment, a polyamide such as nylon-6 and an anhydride functionalized elastomer such as an EPDM rubber grafted with maleic anhydride are first melt-blended. The resulting composition is then blended with a thermoplastic copolymer of an .alpha.,.beta.-unsaturated carboxylic acid anhydride such as maleic anhydride and a monovinyl aromatic monomer such as styrene. The moldable polymer blends thus obtained are suitable for use as engineering resins.
