Abstract: A process to produce a copolyester is provided comprising: a. polymerizing 1) at least one terephthalate monomer; 2) about 85 to about 96 mole% of ethylene glycol; and 3) 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-tetramethy-1,3-cyclobutane diol residues (TMCD); in the presence of a germanium catalyst to produce the copolyester; wherein the germanium catalyst is present in the copolyester at a concentration of about 5 to about 500 ppm based on elemental germanium; wherein the diacid is based on the substantially equal diacid equivalents of 100 mole% to diol equivalence of 100 mole% for a total.

Abstract: A process of producing an article by an extrusion blow molding manufacturing process is provided comprising: melting a copolyester in an extruder to produce a molten copolyester; extruding the molten copolyester through a die to form a tube of molten copolyester parison; clamping a mold having the desired finished shape around the parison; blowing air into the parison causing the parison to stretch and expand to fill the mold to produce a molded article; cooling the molded article; ejecting the article from the mold; and removing excess plastic from the article; wherein the copolyester comprises: at least one terephthalate monomer residue; ethylene glycol residues; a combination of diethylene glycol and at least one glycol residue selected from the group consisting of 1,4-cyclohexanedimethanol residues, monopropylene glycol residues, and 2,2,4,4-tetramethyl-1,3-cyclobutane diol residues; and a germanium catalyst present in the copolyester at a concentration of about 5 to about 500 ppm based on elemental germanium.

Abstract: Extrusion blow molded (EBM) articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxlyic acid component comprises at least 90 mole% terephthal- ic acid residues. The glycol component comprises at least 88 mole% ethylene glycol residues and 7 to 12 mole% residues of 1,4-cyclohexanedimethanol. Such EBM articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.
