Abstract
Reinforced thermoplastic compositions comprised of compatible combinations of a polyphenylene ether resin, polyamide resin, and glass fibers can be impact modified with a modifying agent comprising a partially hydrogenated diblock copolymer of styrene and ethylene/propylene which result in molding compositions having improved thermal aging characteristics.
