ABSTRACT:
Polyphenylene ether resin/polypropylene resin compositions are disclosed which have improved heat deflection temperature and stiffness. The improvements result from the use of a polyphenylene ether resin having an intrinsic viscosity of below about 0.30 dl./gm. The compositions may further comprise an impact modifier.
