PURPOSE: Provided is a polyester resin composition which shows excellent hydrolysis resistance, electrical property even under environment of high temperature and high humidity, and can minimize the lowering of fluidity. CONSTITUTION: The polyester resin composition comprises 100 parts by weight of polybutylene terephthalate and 0.1-7 parts by weight of polycarbonate-based additives represented by formula 1(wherein R1-R10 represent a hydrogen atom, an alkyl group having C1-C3, an amine group, a -OH group, and l is an integer of 30-300). The polyester resin composition shows 60-90% of dielectric breakdown voltage of moulding(produced from the composition) after PCT(Pressure cooker test) at 121 deg.C for 100 hours. |
