ABSTRACT:
Novel compatibilized polyphenylene ether-polyamide compositions are provided by this invention, comprising polyphenylene ether resin, polyamide resin, a compatibilizing agent, and a melt flow-improving compound. The compatibilizing agent may be selected from a wide variety of materials, such as saturated aliphatic polycarboxylic acids or derivatives thereof; various silane compounds; and functionalized polyphenylene ethers. A specific example of a compatibilizer is citric acid. Specific examples of melt flow-improving compounds are stearic acid, oleic acid, and linolenic acid.
