More Information
Summary:A thermoplastic composition includes a poly(arylene ether), a poly(alkenyl aromatic) resin, a polyolefin, a hydrogenated block copolymer of alkenyl aromatic compound and a conjugated diene having an alkenyl aromatic content of about 40 to about 90 weight percent, and an unhydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene. The composition exhibits excellent stiffness-impact strength balance, low property variability, and long melt hang time. L'invention concerne une composition thermoplastique contenant un poly(arylène éther), une résine poly(alkényl aromatique), un polyoléfine, un copolymère bloc hydrogéné de composant aromatique alkényl et un diène conjugué possédant un contenu aromatique alkényl d'environ 40 % à 90 % par poids et un copolymère bloc non hydrogéné de composant aromatique alkényl et un diène conjugué. Cette composition présente un excellent équilibre de force d'impact sur la rigidité, une faible variation de propriété et une résistance de longue durée à la fusion.
