    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.

    摘要: Functionalized polyphenylene ether compositions are provided which are particularly useful for effecting compatibility for a blend of polyphenylene ether resin and a polyamide resin. The functionalized-polyphenylene ether is the reaction product of a polyphenylene ether polymer and a compound having the general formula (i)--Z--(ii), wherein group (i) is a polyphenylene ether-philic moiety such as acyl chloride, group (ii) is a polyamide-philic moiety such as dicarboxylic acid anhydride, and Z is a divalent hydrocarbon radical providing a covalent linkage between groups (i) and (ii). An example of the compound having general formula (i)--Z--(ii) is trimellitic anhydride acid chloride.
