Abstract:
Described are bottles(s) comprising at least one polyester composition comprising at least one polyester which comprises terephthalic acid residues; 30 to 40 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 60 to 70 mole % of 1,4-cyclohexanedimethanol residues, wherein the inherent viscosity of said polyester is from 0.50 to 0.68 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.5 g/100 ml at 25° C.; wherein said 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; 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 said polyester composition contains no polycarbonate.
