PROCESS OF MAKING ARTICLES COMPRISING COPOLYESTERS PRODUCED WITH GERMANIUM CATALYSTS
A copolyester is provided comprising: a. terephthalate acid residues; b. about 85 to about 96 mole% of ethylene glycol residues; c. about 4 to about 15 mole% of a. combination of diethylene glycol (DEG) residues and at least one glycol residue selected from the group consisting of 1,4-cyclohexanedim...

Summary: | A copolyester is provided comprising: a. terephthalate acid residues; b. about 85 to about 96 mole% of ethylene glycol residues; c. about 4 to about 15 mole% of a. combination of diethylene glycol (DEG) residues 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 terephthalate monomer is based on the substantially equal diacid equivalents of 100 mole% to diol equivalence of 100 mole% for a total of 200 mole%. |
