Abstract:
1. A polyester composition comprising: (I) at least one polyester which comprises: (II) at least one thermal stabilizer chosen from at least one of alkyl phosphate esters, aryl phosphate esters, mixed alkyl aryl phosphate esters, reaction products thereof, residues thereof or mixtures thereof; wherein the total mole % of the dicarboxylic acid component is 100 mole %, wherein the total mole % of the glycol component is 100 mole %; wherein the inherent viscosity of the polyester is from 0.60 to 0.75 dL/g as determined in 60/40 (wt/wt) phenol/ tetrachloroethane at a concentration of 0.25 g/50 ml at 25° C.; wherein the polyester has a Tg from 100 to 130° C.; wherein said polyester composition contains no polycarbonate; wherein the melt viscosity of said polyester is less than 10,000 poise as measured at 1 radian/second on a rotary melt rheometer at 290° C.; and wherein the polyester has a notched Izod impact strength of at least 7.5 ft-lb/inch at 23° C. according to ASTM D256 with a 10-mil notch in a ⅛ inch thick bar.
