Abstract
Disclosed are resin compositions comprising (a) a polyphenylene ether resin or a polyamide resin or a polyester resin; (b) a glycidyl moiety-styrenic grafted propylene polymer material in combination with a styrenic polymer copolymerized with a glycidyl moiety; optionally (c) (1) one or more monoalkenyl aromatic hydrocarbon-conjugated diene block copolymers, hydrogenated products thereof or mixtures thereof, with or without (2) olefin copolymer rubber; and optionally (d) a propylene polymer material. The compositions exhibit increased resistance to delamination, indicating improved compatibility between the engineering resins and propylene polymer material.
