Copolyester blends

There is provided a copolyester composition comprising at least one copolyester and at least one polymer component; wherein the copolyester comprises: a. A terephthalate acid residue; b. From about 85 to about 96 mol% of ethylene glycol residues; c. From about 4 to about 15 mol% of a combination of a diethylene glycol (DEG) residue and at least one diol residue selected from the group consisting of a 1, 4-cyclohexanedimethanol residue (CHDM), a propylene glycol residue (MPG), and a 2, 2, 4, 4-tetramethyl-1, 3-cyclobutanediol residue (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 substantially equal 100 mol% diacid equivalents to 100 mol% diol equivalents, totaling 200 mol%. 提供了一种共聚酯组合物，其包含至少一种共聚酯和至少一种聚合物组分；其中所述共聚酯包含：a.对苯二甲酸酯酸残基；b.大约85至大约96摩尔％的乙二醇残基；c.大约4至大约15摩尔％的二乙二醇(DEG)残基与至少一种选自1，4-环己烷二甲醇残基(CHDM)、一丙二醇残基(MPG)和2，2，4，4-四甲基-1，3-环丁二醇残基(TMCD)的二醇残基的组合；和d.基于元素锗以大约5至大约500ppm的浓度存在
