Abstract:
A polyamide resin shaped article comprising (A) 92 to 99.7 mass % of a polyamide resin produced by polycondensation of a diamine component containing 70 mol % or more of m-xylylenediamine and a dicarboxylic acid component containing 70 mol % or more of a straight-chain, aliphatic &agr;,&ohgr;-dicarboxylic acid having 4 to 12 carbon atoms, and (B) 8 to 0.3 mass % of a silicate prepared by treating a layered silicate with an organic swelling agent with the proviso that the mass percentages are based on a sum of the polyamide resin A and the silicate B, wherein the polyamide resin shaped article is produced by:preliminarily melt-kneading 70 to 95 mass % of the polyamide resin A and 30 to 5 mass % of the silicate B, on the basis of a sum of the polyamide resin A and the silicate B, to prepare a resin composition C; melt-kneading 3 to 40 mass % of the resin composition C and 97 to 60 mass % of the polyamide resin A, on the basis of a sum of the resin composition C and the polyamide resin A, at the time of producing the polyamide resin shaped article; and then shaping or molding the melt-kneaded product into the polyamide resin shaped article in which the silicate B is uniformly and finely dispersed throughout the polyamide resin A.
