Abstract
A resin composition suitable for injection moulding and having excellent heat resistance, impact resistance and crack resistance, which is composed of polyphenylene ether and rubber-reinforced styrene resin and an amount of volatile matters in the resin having molecular weight of about 300 or less is 5000 ppm or less. This resin composition is prepared by melting and kneading the two resins above in an extruder with a vent under keeping the vent part under reduced pressure.
