A thermoplastic resin composition which is produced by mixing a thermoplastic resin with fibrous xonotlite the surface of which has been coated beforehand with a surfactant and which has a BET specific surface area of 21 m<2>/g or larger, an average fiber length of 1 to 5 mu m, and an average fiber diameter of 0.1 to 0.5 mu m in a weight ratio of 99.5/0.5 to 20/80 and kneading the resultant mixture with heating in the presence of 0.2 to 10 wt.% coupling agent based on the fibrous xonotlite. In the resin composition, the fibrous xonotlite has been reduced to fine particles, is evenly dispersed, and strongly bonds to the thermoplastic resin. The composition is hence excellent especially in impact resistance and flexural strength. It is advantageously usable especially in producing molded resins for automotive parts, electrical/electronic parts, precision work parts, etc. |
