PURPOSE:To produce an aromatic polyester composition with high hydrolytic resistance, excellent molding flowability and weather resistance, by adding a specific epoxy compound, a hindered phenol compound and/or a sulfur- containing ester. CONSTITUTION:(A) 100pts.wt. of an aromatic polyester, preferably PETE, PBTF of 1.15-2 relative viscosity, are mixed with (B) 0.01-10pts.wt., preferably 0.05-5pts.wt. of an epoxy compound of formula I (Ar is preferably 6-20C aromatic, alicyclic group, preferably 4-phenylene; n is 0, 1-20, preferably 0, 1-10) and (C) 0.01-5pts.wt., preferably 0.05-3pts.wt. of a hindered phenol consisting of formula II (R is 1-20C alkyl) units and having 500 or more molecular weight and/or a sulfur-containing ester (preferably didodecyl thiodipropionate). |
