    Abstract: PROBLEM TO BE SOLVED: To obtain the subject polyamide resin composition that can suppress the decomposition of organic substances distributing between the silicate salt layers and can retain the rigidity of a high level by exchanging the exchangeable metal ions distributing between the layers of laminar silicate salt with a specific organic substance. SOLUTION: (A) A polyamide resin (preferably nylon 6 or nylon 66) and (B) a laminar silicate salt in which the exchangeable metal ions distributing between the layers are exchanged with a polyamide of which the amino terminal groups are ionized (preferably an amino terminal-ionized and alcohol-soluble polyamide) are melt-kneaded to give the objective composition. The inorganic ash content in this composition is 0.1-40 wt.%. In a preferred embodiment, the polyamide bearing ionized amino terminals is selected from a nylon 6/nylon 66 copolymer and the like. The component B is prepared by dissolving a polyamide resin in an alcohol, adding acidic water to the polyamide solution to ionize the amino terminal groups and the ionized polyamide is mixed with the laminar silicate salt.
