Abstract: A thermoplastic polyester resin composition includes a thermoplastic polyester resin (A), and with respect to 100 parts by weight thereof, 1 to 40 parts by weight of an elastomer (B), 15 to 100 parts by weight of a fibrous reinforcing filler (C), 0.4 to 5 parts by weight of a silicone compound (D) and 0.1 to 10 parts by weight of an epoxy compound (E) having an epoxy equivalent of 200 to 400 g/eq. The thermoplastic polyester resin composition has excellent alkaline resistance, hydrolysis resistance, and heat shock resistance, and can form a molded article composed of the thermoplastic polyester resin composition.

Abstract: Provided is a thermoplastic polyester resin composition comprising 100 parts by weight of (A) a non-liquid crystal thermoplastic polyester resin, 45 to 150 parts by weight of (B) a thermoplastic resin that is different from the non-liquid crystal thermoplastic polyester resin and has a dielectric loss tangent of not more than 0.005 when measured at a frequency of 5.8 GHz by the cavity resonance perturbation method, 2 to 20 parts by weight of (C) a compatibilizer having at least one reactive functional group selected from epoxy, acid anhydride, oxazoline, isocyanate, and carbodiimide groups, and 0.2 to 5 parts by weight of (D) at least one compound selected from tertiary amines, amidine compounds, organic phosphines and salts thereof, imidazoles, and boron compounds, wherein the ratio of the sum of the thermoplastic resin (B) and the compatibilizer (C) is in the range of 50 to 150 parts by weight and the weight ratio (B)/(C) of the thermoplastic resin (B) to the compatibilizer (C) is in the range of 8 to 50. The thermoplastic polyester resin composition can be molded into an article with low dielectric properties, excellent mechanical properties, and high bondability to metals.
