摘要： A solid concentrate is provided having a combination of a transition metal present in an amount ranging from 1,000 to 40,000 ppm (weight by metal) and a polyester polymer present in an amount of at least 40 wt. % based on the weight of the concentrate. Concentrates made with highly modified polyester polymers are easy to compound with transition metals forming less brittle polymer upon melt extrusion. Bottle preforms and oxygen scavenging bottles can be made from these concentrates by combining solid polyester particles, solid polyamide particles, and solid these concentrate particles c into an melt processing zone, forming a melt, and forming an article directly from the melt. The b* color and the L* color and the haze levels of the preforms are improved over the preforms made with liquid carriers instead of solid concentrates. The particles are also advantageously simultaneously dried in a drying zone under conditions effective to at least partially remove moisture from the blend to thereby further improve the b* color and L* color.

摘要： The present invention concerns a method for forming an article by combining a polyester polymer and an oxygen scavenging composition comprising a polyamide in the presence of zinc and a cobalt in a melt processing zone to form a melt; and forming an article such as a sheet or preform from the melt. Also provided are molten formulated polyester polymer compositions containing a blend of a polyethylene terephthalate polymer and a polyamide polymer along with zinc and cobalt. Articles made from the composition are resistant to the transmission of oxygen, possess short induction periods, and have high capacity for sustaining lengthy periods of low oxygen transmission through the wall of the article.
