Abstract

To provide a thermoplastic resin composition which comprises a fluorine-containing polymer having a molecular weight of 5.times.10.sup.2 to 5.times.10.sup.5 and 2.times.10.sup.2 to 1.times.10.sup.5 methylol groups per 1.times.10.sup.6 carbon atoms at its molecular chain ends and a liquid crystal polyester or in addition a perfluoro type resin having less than 2.times.10.sup.2 methylol groups mentioned above, and has improved shrinkage from mold dimensions and dimensional stability represented by a coefficient of linear expansion with maintaining excellent characteristics of the fluorine-containing resin, such as thermal resistance, chemical resistance, weather resistance, surface properties (non-stickiness, excellent friction property), antisoil property and dielectric property.
