A thermoplastic resin composition comprising a fluoropolymer having a molecular weight of 5x10² to 5x10⁵ and containing 2x10² to 1x10⁵ terminal methylol groups per 1x10⁶ carbon atoms, a liquid crystal polyester, and optionally further a perfluororesin containing less than 2x10² terminal methylol groups per 1x10⁶ carbon atoms. The composition can be improved in dimensional stability represented by molding shrinkage and coefficient of linear expansion without detriment to the characteristics inherent in fluororesins, such as excellent resistances to heat, chemical and weathering, surface characteristics (e.g. nonstickiness and low friction), stainproofness, and electrical insulation.
