    Abstract: This invention relates to a polyester composition comprising: (i) diacid residues comprising at least 80 mole percent, based on the total moles of diacid residues, of one or more residues of: terephthalic acid, naphthalenedicarboxylic acid, 1,4-cyclohexanedicarboxylic acid, or isophthalic acid; and (ii) diol residues comprising from about 25 to about 70 mole percent, based on the total moles of diol residues, of the residues of 1,4-cyclohexanedimethanol, and from about 75 to about 30 mole percent, based on the total moles of diol residues, of the residues of 1,3-propanediol. This invention has surprising improved impact strength at low temperatures.

    CPC classification number: C08G63/199

    Abstract: Disclosed are amorphous copolyesters having an inherent viscosity (IV) of about 0.5 to 1.1 dL/g measured at a temperature of 25° C. at 0.5 g/dL concentration in a solvent mixture of symmetric tetrachloroethane and phenol having a weight ratio of symmetric tetrachloroethane to phenol of 2:3 comprising (1) a diacid component comprising about 90 to 100 mole percent terephthalic acid residues and 0 to about 10 mole percent isophthalic acid residues; and (2) a diol component comprising about 10 to 70 mole percent 1,4-cyclohexanedimethanol residues and about 90 to 30 mole percent neopentyl glycol residues; wherein the amorphous copolyesters comprises 100 mole percent diacid component and 100 mole percent diol component. The amorphous copolyesters are useful in the manufacture or fabrication of medical devices which have improved resistance to degradation upon exposure to lipids, as a profile produced by profile extrusion and as an injection molded article. Also, a method of melt processing the amorphous copolyester is disclosed which allows for performing a minimal drying or no drying of the copolyester prior to melt processing.

    Abstract translation: 公开了在对称四氯乙烷和苯酚的溶剂混合物中在25℃的温度下以0.5g / dL的浓度测量的具有约0.5至1.1dL / g的特性粘度（IV）的无定形共聚酯，其重量比为对称四氯乙烷 至2：3的苯酚，其包含（1）包含约90至100摩尔％对苯二甲酸残基和0至约10摩尔％间苯二甲酸残基的二酸组分; 和（2）包含约10至70摩尔％的1,4-环己烷二甲醇残基和约90至30摩尔％的新戊二醇残基的二醇组分; 其中所述无定形共聚酯包含100摩尔％的二酸组分和100摩尔％的二醇组分。 无定形共聚酯可用于制造或制造具有改善的抗暴露于脂质时的降解性的医疗装置，作为通过型材挤出产生的轮廓和注模制品。 此外，公开了熔融加工无定形共聚酯的方法，其允许在熔融加工之前进行最小的干燥或不干燥共聚酯。
