Articles, including water bottle(s) having a weight from 200 to 800 grams comprising a polyester composition comprising at least one polyester which comprises: (a) a dicarboxylic acid component comprising terephthalic acid residues; optionally, aromatic dicarboxylic acid or aliphatic dicarboxylic acid residues; and (b) a glycol component comprising 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 total mole % of the dicarboxylic acid component is 100 mole %, and the total mole % of the glycol component is 100 mole and the inherent viscosity of the 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&#xb0; C.; and wherein the polyester has a Tg of from 100 to 140&#xb0; C.; and wherein the polyester composition contains no polycarbonate.

Containers comprising polyester compositions which comprise cyclobutanediol

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&#xb0; C.; wherein said polyester has a notched Izod impact strength of at least 7.5 ft-lb/inch at 23&#xb0; C. according to ASTM D256 with a 10-mil notch in a &#x215b;-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&#xb0; C.; and wherein said polyester composition contains no polycarbonate.

This invention relates to a baby bottle made from a polyester composition comprising a polyester further comprising 80 to 100 mole % terephthalic acid residues, 0 to 20 other diacid residues, 30 to 40 mole % 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues and 60 to 70 mole % 1,4-cyclohexanedimethanol residues, wherein the total diol residues equal 100 mole % and the total diacid residues equal 100 mole %. These baby bottles are unique in that they provide an alternative to baby bottles made from polycarbonate and they provide good heat resistance, good toughness, and good chemical resistance.
