Abstract: The present invention is to a composition made from a polyester produced by the acid or ester polyester process, a cobalt salt and a base, preferably an alkaline metal base. The composition can be made by blending a cobalt salt with a polyester which has been polymerized in the presence a alkaline metal ion derived from a basic alkaline metal compound, e.g. alkaline metal base or basic alkaline metal salt. The composition may optionally comprise an ionic compatibilizer, which may further be blended with a partially aromatic polyamide. This blend can be processed into a container having both active and passive oxygen barrier with an improved color and clarity than that achieved by cobalt alone. The use of the cobalt salt in combination with the base can also be used to improve the color of recycled polyester durin processing.
Abstract translation: 本发明是由酸或酯类聚酯方法制得的聚酯，钴盐和碱，优选碱金属碱制成的组合物。 该组合物可以通过将钴盐与在碱性碱金属化合物的碱金属离子存在下聚合的聚酯混合来制备， 碱金属碱或碱性碱金属盐。 组合物可以任选地包含离子增容剂，其可以进一步与部分芳族聚酰胺共混。 该混合物可以被加工成具有主动和被动氧气屏障的容器，其颜色和透明度比单独使用钴获得的更好的颜色和透明度。 使用钴盐与碱组合也可以用于改善再循环聚酯干燥剂加工的颜色。
