The present invention relates to a polyamide resin composition comprising:

Polyamide resin composition having improved weathering resistance and its molded products

A resin composition comprising predetermined amounts of a specific polyamide resin (A), a modified polyphenylene ether resin (B), a fibrous inorganic filler (C) having an average fiber-diameter of 10 .mu.m or less, a powdery inorganic filler (D) having an average particle diameter of 10 .mu.m or less, an epoxy resin (E) and a copper compound (F-1) and/or a powdery phenolic resin (F-2); a molded article formed from the resin composition; and a lamp reflector formed from the molded article. The molded article formed from the above resin composition can give an automotive lamp reflector excellent in resistance to heat generated when a lamp is on, rigidity at high temperatures, clear reflection performance on a mold article surface, adhesion to deposited aluminum and adhesion to a primer coating composition.

Resin composition for molding materials

A process for preparing a polyamide is provided. The polyamide is prepared by effecting direct polycondensation reaction of a dicarboxylic acid component containing at least 80 mole % of adipic acid and a diamine component containing at least 70 mole % of m-xylylene diamine under an atmosphere of an inert gas and at atmospheric pressure at a controlled temperature which is higher than the melting point of the dicarboxylic acid component and which can maintain the reaction mixture in a uniformly-fluidized state throughout the reaction.
