Moldable polyester resin compositions and molded articles therefrom include, based on the total weight of all resin components: (A) between 2 to 98% by weight of a compatibilizing metal sulfonate group-containing aromatic polyester copolymer which is the polycondensation reaction product of (a) an aromatic dicarboxylic acid or its ester-forming derivative, (b) a diol compound or its ester-forming derivative, and (c) an ester-forming compound containing a metal sulfonate group; (B) between 2 to 98% by weight of an additive resin which is one of (B-I) an olefin copolymer which is the copolymerization reaction product between an olefin with at least one of an (alpha),(beta)-unsaturated carboxylic acid or its derivative and a vinyl alcohol or its ester, and (B-II) a polyamide resin; and, optionally (C) between 0 to 96% by weight of a non-compatibilizing aromatic polyester resin. The ester-forming compound containing a metal sulfonate group is preferably incorporated into the main polymer chain of the compatibilizing aromatic polyester resin in an amount between 0.01 to 15 molar percent. |
