摘要：
A piston guide ring for use in a piston-cylinder assembly includes a compatibilized polyamide-poly(arylene ether) blend. The compatibilized polyamide-poly(arylene ether) blend includes about 35 to about 95 parts by weight polyamide and about 5 to about 65 parts by weight poly(arylene ether), based on 100 parts by weight total of the polyamide and the poly(arylene ether). The piston guide rings provide improved compressive strength at elevated operating temperatures, more isotropic mold shrinkage, and reduced moisture absorption compared to piston guide rings prepared from polyamide.
