    摘要: The invention relates to a copolyester having an inherent viscosity ranging from about 0.4 to about 1.4 and a cold crystallization temperature ranging from about 120 to about 160.degree. C. Such copolyesters comprise the reaction product of a glycol component comprising from about 85 to about 100 mole % of 1,3-propanediol, a dibasic acid component comprising from about 85 to about 100 mole % of a dibasic acid selected from terephthalic acid, napthalenedicarboxylic acid, anhydrides, acid chlorides, and lower alkyl esters thereof, and mixtures thereof, and from about 5 to about 15 mole % of a comonomer. The presence of the comonomer lowers the crystallization temperature of the copolyesters according to the invention such that amorphous preforms can be easily molded from the copolyesters. Such amorphous preforms are readily stretch blow molded into bottles or other container shapes or may be injection molded into various shapes or objects or extruded into film or sheeting. Accordingly, in another embodiment of the invention relates to film and containers prepared from the copolyester composition described above. The films and containers according to the invention have improved gas barrier properties such that they may be used for packaging perishable goods, such as beverages, foods, and cosmetics.

    摘要翻译: 本发明涉及具有约0.4至约1.4的特性粘度和约120至约160℃的冷结晶温度的共聚多酯。这种共聚酯包含二醇组分的反应产物,其包含约85至约100摩尔 %的1,3-丙二醇,二元酸组分,其包含约85至约100摩尔%的选自对苯二甲酸,萘二甲酸,酸酐,酰氯和其低级烷基酯的二元酸及其混合物,以及 约5至约15摩尔%的共聚单体。 共聚单体的存在降低了根据本发明的共聚酯的结晶温度,使得非晶预成型体可以容易地从共聚酯模塑。 这种无定型预成型件容易地拉伸吹塑成瓶或其它容器形状,或者可以注塑成各种形状或物体或挤出成膜或片材。 因此,在本发明的另一个实施方案中涉及由上述共聚聚酯组合物制备的膜和容器。 根据本发明的薄膜和容器具有改进的阻气性能,使得它们可用于包装易腐食品,例如饮料,食品和化妆品。

    摘要: Amorphous copolyesters containing residues derived from 2,2′-[2,2-](sulfonylbis(4,1-phenyleneoxy))bis(ethanol). They exhibit enhanced heat distortion temperatures and glass transition temperatures without a significant increase in viscosity at low shear rates. The amorphous copolyesters also have improved resistance to attack by lipid solutions and are readily molded and extruded to form medial devices such as connectors, tubes, etc. which are useful for transport of lipids and other medical solutions.

    摘要: An amorphous copolyester having a maximum melt viscosity at 1 radian/second and at about 260 to about 290° C. of about 12000 poise, a glass transition temperature ranging from about 88° C. to about 120° C., and an inherent viscosity of at least about 0.6 dl/g. The amorphous copolyesters comprise the reaction product of a diol component and a dicarboxylic acid component. The diol component comprises residues of from about 5.0 to about 50 mole % of 2,2′-(sulfonylbis (4,1-phenyleneoxy))-bis(ethanol) which has the following chemical formula: and from about 50 to about 95 mole % of a mixture of at least two diols selected from the group consisting of ethylene glycol, neopentyl glycol, 1,3-propanediol, 1,4-butanediol, 1,4-cyclohexanedimethanol, and mixture thereof. The dicarboxylic acid component comprises residues of terephthalic acid, isophthalic acid, 1,4-cyclohexandedicarboxylic acid, 2,6-naphthalene dicarboxylic acid and mixtures thereof. The amorphous copolyesters according to the invention have relatively low melt viscosities and relatively high glass transition temperatures. Because of the low melt viscosities and high glass transition temperatures, copolyesters with increased IV or molecular weight can easily be obtained. The copolyesters according to the invention can be used for molded or extruded articles, sheets, and films. Accordingly, the invention also relates to molded and extruded articles, sheets, and films made from a copolyester as described above. Additionally, articles, sheets, and films according to the invention have improved gas barrier properties such that they may be used for packaging perishable goods, such as beverages, foods and cosmetics, as well as other oxygen sensitive products such as inks and adhesives.

    摘要翻译: 无定形共聚酯,其熔体粘度为1弧度/秒,约260至290℃,熔点约为12000泊,玻璃化转变温度范围为约88℃至约120℃,特性粘度 至少约0.6dl / g。 无定形共聚酯包括二醇组分和二羧酸组分的反应产物。 二醇组分包括具有以下化学式的2,2'-(磺酰基双(4,1-亚苯氧基)) - 双(乙醇)的约5.0-约50摩尔%的残基和约50-约95摩尔 %的至少两种选自乙二醇,新戊二醇,1,3-丙二醇,1,4-丁二醇,1,4-环己烷二甲醇及其混合物的二醇的混合物。 二羧酸组分包括对苯二甲酸,间苯二甲酸,1,4-环己二羧酸,2,6-萘二甲酸及其混合物的残留物。 根据本发明的无定形共聚酯具有相对低的熔体粘度和相对较高的玻璃化转变温度。 由于熔体粘度低和玻璃化转变温度高,因此可以容易地获得IV或分子量增加的共聚酯。 根据本发明的共聚酯可用于模制或挤出制品,片材和薄膜。 因此,本发明还涉及由如上所述的共聚酯制成的模制和挤压制品,片材和薄膜。 此外,根据本发明的制品,片材和薄膜具有改进的阻气性能,使得它们可用于包装易腐食品,例如饮料,食品和化妆品,以及其它氧敏感产品如油墨和粘合剂。
