摘要： Polyester compositions are disclosed that include polyester polymers or copolymers having incorporated therein titanium nitride particles that provide one or more of the following advantages: improving the reheat properties of the compositions, improving the color of the compositions through reduced yellowness, and improving the UV-blocking properties of the compositions. Processes for making such compositions are also disclosed. The titanium nitride particles may be incorporated in the polyester by melt compounding, or may be added at any stage of the polymerization, such as during the melt-phase of the polymerization. A range of particle sizes may be used, as well as a range of particle size distributions. The polyester compositions are suitable for use in packaging made from processes in which a reheat step is desirable, or decreased yellowness is desired, or increased resistance to the effects of ultraviolet light is desired, or any combination of the foregoing.
摘要翻译： 公开了聚酯组合物，其包括具有纳入其中的氮化钛颗粒的聚酯聚合物或共聚物，其提供一个或多个以下优点：改善组合物的再热性能，通过减少黄度改善组合物的颜色，并改善UV-阻断 组合物的性质。 还公开了制备这种组合物的方法。 可以通过熔融配混将氮化钛颗粒引入聚酯中，或者可以在聚合的任何阶段例如在聚合的熔融相期间加入。 可以使用一定范围的粒度，以及一定范围的粒度分布。 聚酯组合物适用于由期望再热步骤或期望减少黄色的方法制成的包装或期望提高对紫外光效果的耐受性，或上述任何组合。

摘要： Polymer blends suitable for packaging are disclosed that include a transition metal; one or more polyamide homopolymers or copolymers; and one or more polyethylene terephthalate homopolymers or copolymers obtained by a melt phase polymerization using a catalyst system comprising aluminum atoms in an amount, for example, from about 3 ppm to about 60 ppm and one or more alkaline earth metal atoms, alkali metal atoms, or alkali compound residues in an amount, for example, from about 1 ppm to about 25 ppm, in each case based on the weight of the one or more polyethylene terephthalate homopolymers or copolymers The polymer blends disclosed exhibit improved oxygen-scavenging activity compared with blends made using polymers prepared with conventional catalyst systems.
