  • Patent number: 5175211
    Abstract: A thermoplastic resin composition comprises a polyphenylene ether having a reduced viscosity within the range of 0.30 dl/g or more and less than 0.45 dl/g, an aliphatic polyamide, a specified compatibilizing agent, and a rubber material. The composition has a high in heat distortion temperature and is superior in processability.
