Abstract

This invention provides a flame-retardant resin composition comprising:(A) 100 parts by weight of a thermoplastic resin other than a thermotropic liquid crystal polymer,(B) 0.01 to 50 parts by weight of a thermotropic liquid crystal polymer, and(C) 1 to 30 parts by weight of a halogen-free phosphazene compound,the invention providing a novel flame-retardant resin composition which is free of the problems arising due to the presence of halogen element, the composition being excellent in flame retardancy, mechanical properties, molding processability and the like, and being unlikely to cause dripping.
