    Abstract: To increase the melt strength and increase high shear thinning of a polyester composition, a polar chain terminator that contains a nonionic group or an ionic group neutralized with a counterion is added at a level of 0.05 to 20 mole percent. Optionally, up to 2.0 mole percent of a trifunctional or greater branching agent is added to the polyester composition. Optionally, up to 30 mole percent of a polar midchain difunctional monomer that contains a nonionic group or an ionic group neutralized with a counterion is added. The polyester composition is based on 100 mole percent diacid component and 100 mole percent glycol component.

    Abstract: A reactor grade copolyester composition, as well as a heat-shinkable film made therefrom, unexpectedly has higher ductility than a multi-component blend of copolyesters with the same monomer concentrations. The reactor grade copolyester composition is made from a diacid component of at least about 90 mole percent and a diol component of (a) about 72 to about 88 mole percent ethylene glycol, about 10 to about 15 mole percent 1,4-cyclohexanedimethanol, and about 2 to about 13 mole percent diethylene glycol, or (b) about 59 to about 77.5 mole percent ethylene glycol, about 15 to about 28 mole percent 1,4-cyclohexane-dimethanol, and about 7.5 to about 13 mole percent diethylene glycol. Further, the heat-shrinkable film may be produced to closely match the shrink characteristics of polyvinyl chloride by varying the amounts of the diol components of the reactor grade copolyester composition. Furthermore, a reactor grade copolyester composition has a b* color value of -1.0 to less than 4.5, wherein the diacid component is at least about 90 mole percent terephthalic acid and the diol component is about 52 to about 88 mole percent ethylene glycol, about 10 to about 28 mole percent 1,4-cyclohexane-dimethanol, and about 2 to about 20 mole percent diethylene glycol.

    Abstract translation: 反应物级共聚酯组合物以及由其制成的可热切薄膜意外地具有比具有相同单体浓度的共聚酯的多组分共混物更高的延展性。 反应器级共聚酯组合物由至少约90摩尔％的二酸组分和（a）约72-约88摩尔％乙二醇，约10-约15摩尔％1,4-环己烷二甲醇的二醇组分和 约2至约13摩尔％的二甘醇，或（b）约59至约77.5摩尔％的乙二醇，约15至约28摩尔％的1,4-环己烷二甲醇和约7.5至约13摩尔％的二甘醇。 此外，可以通过改变反应器级共聚酯组合物的二醇组分的量来生产热收缩膜以与聚氯乙烯的收缩特性紧密匹配。 此外，反应器级共聚酯组合物的ab *颜色值为-1.0至小于4.5，其中二酸组分为至少约90摩尔％对苯二甲酸，二醇组分为约52-约88摩尔％乙二醇，约10 至约28摩尔％的1,4-环己烷二甲醇，和约2至约20摩尔％的二甘醇。
