PURPOSE:To provide the titled compsn. which has excellent nucleation characteristics, crystallizability, rigidity and impact strength, allows a molding cycle to be shortened and gives moldings which neither cause deformation nor form voids, consisting of a polyamide (nylon 46) resin and specified fine particles. CONSTITUTION:95-99.999wt% polyamide (nylon 46) resin having an MW of 4,000 or above, obtd. by polymerizing 1, 4-diaminobutane and adipic acid, and 0.001-5wt% fine particles (e.g. metal oxides such as Al2O3, phosphorus compd., graphite, talc, high-melting polymer powder, metal salts of naphthenic acid or higher fatty acids, ionomer resin, etc.) having an average particle size of 5mu or below, a decomposition point of 200 deg.C or above and a surface having active moiety capable of adsorbing or absorbing NH3, Cl2, water, H2, CO2, CH4, CH3OH, HCl or gases such as NO, are melt-kneaded together to thereby disperse the particles in the polymer. |
