POLYAMIDE RESIN COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a composition excellent in strength and elastic modulus by dispersing a layered silicate, at a molecular level, into a polyamide having meta-xylylene diadipamido as the main unit. SOLUTION: The polyamide resin composition containing the layered silicate of 0.01-40 mass% in the polyamide obtained from a dicarboxylic acid component having an adipic acid as a main ingredient and a diamine component having meta-xylylene diamine as the ingredient is characterized in that the distance of layer space in the silicate is 20Åor more. The method for producing the composition is characterized in that the diamine component is added to the mixture of the dicarboxylic acid component and the layered silicate in the melting state to polycondensate them.
