摘要：
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° C.； and wherein the polyester has a Tg of from 100 to 140° C.； and wherein the polyester composition contains no polycarbonate.
