  • Polyphenylene ether composition
    Patent number: 4863997
    Abstract: A polyphenylene ether composition comprising (a) a polyolefin resin, (b) a polyphenylene ether resin, and (c) a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene which contains more than 45% by weight and up to 80% by weight of a repeating unit derived from the alkenyl aromatic compound. The composition has a high flexural modulus and excellent mechanical properties, such as impact resistance.
