Zusammenfassung:	An article is provided comprising a copolyester; wherein the copolyester comprises: a. at least one terephthalate monomer residue; b. about 85 to about 96 mole % of ethylene glycol residues; c. about 4 to about 15 mole % of a combination diethylene glycol (DEG) and at least one glycol residue selected from the group consisting of 1,4-cyclohexanedimethanol residues (CHDM), monopropylene glycol residues (MPG), and 2,2,4,4-tetramethyl-1,3-cyclobutane diol residues (TMCD); and d. a germanium catalyst present in the copolyester at a concentration of about 5 to about 500 ppm based on elemental germanium; wherein the diacid monomer is based on the substantially equal diacid equivalents of 100 mole % to diol equivalence of 100 mole % for a total of 200 mole %.
