摘要: Disclosed is a polyester composition comprising (a) 100 parts by weight of an aromatic polyester; (b) 0.005-10 parts by weight of an epoxy compound of the formula (I): ##STR1## (wherein Ar means C.sub.6 -C.sub.20 aromatic group or C.sub.6 l-C.sub.20 alicyclic group, n means an integer of 0-20); and (c) 1-70 parts by weight of at least one elastomer which has at least one functional group selected from the group consisting of epoxy groups, carboxyl group, carboxylate ester groups, carboxylic acid amide groups, acid anhydride group, imide groups, carboxylate salt groups, hydroxyl group, amino group and cyano group, the elastomer having a tensile modulus of 1-6,000 kg/cm.sup.2. The polyester resin composition of the present invention can easily be molded and the obtained molded article excells in mechanical properties such as impact strength. The obtained molded article also excells in flowability and residence stability during the molding, and in hydrolysis stablity, resistance to thermal cycling and in weatherability.
