Abstract
Abstract The present invention provides a polyamide resin composition which has low water absorption and simultaneously has satisfactory combustion properties. Illustrative compositions contain 20-80 parts by weight of polyamide resin and 80-20 parts by weight of polyphenylene ether resin or a mixture of this resin and polystyrene resin, as well as 0.01-10 parts by weight of a compatibilizer, 1-50 parts by weight of an uncured phenol novolak resin, and 0-80 parts by weight of a rubber component wherein the weights of the compatibilizer, uncured phenol novolak resin and rubber component is based on a total of 100 parts by weight of polyamide and polyphenylene ether resins.
