ABSTRACT:
Polyphenylene ether-polyamide compositions compatibilized with polyfunctional compounds such as aliphatic polycarboxylic acids can achieve improved impact strength and ductility by producing an intermediate polyphenylene ether-polyamide product containing at least some nylon 6,6 and thereafter further compounding the intermediate product with a second polyamide component containing at least some of a polyamide different from nylon 6,6.
