摘要：
The surface gloss and flexural modulus of articles molded from blends of a polyphenylene ether resin and a rubber modified, high impact polystyrene (HIPS) are regulated by controlling the swell index of the HIPS rubber within the range of 8 to 20. Duller surface finishes and higher flexural moduli are achieved with use of higher swell indices, while glossier surfaces and lower flexural moduli are obtained with lower swell indices within this range.
