Abstract: A solid concentrate is provided having a combination of a transition metal present in an amount ranging from 1000 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.

Abstract: The invention relates to polyester/polyamide blend compositions for forming an article having low haze and reduced gas permeability compared to the polyester alone. More specifically, the invention relates to blends of semi-crystalline polyesters such as PET with low molecular weight polyamides and to the containers and packages for food, beverages, cosmetics, pharmaceuticals and personal care products that can be fabricated from these blends.

Abstract: This invention relates to a polyester/zeolite admixture having an excellent gas barrier property and an improved flavor retaining property, and clarity. More particularly, the present invention relates to a polyester/zeolite admixture wherein the zeolite is present in a critical amount of 100 parts per million (ppm) to 1,000 ppm. The present inventors have determined that addition of small- or medium-pore zeolites in a critical amount to a polyester reduces the concentration of acetaldehyde in the polyester without producing haze and thus improves the storage property, flavor retaining property, and fragrance retaining property of containers made from such polyester.

Abstract: Disclosed is a process for a melt processing a polyethylene terephthalate. The polyester particles have at least two melting peaks. The polyester particles may have an It. V. at their surface which is less than 0.25 dL/g higher than the It. V. at their center. The polyester particles may have not been solid stated. The melt processing device comprises a screw with a total length (9), L, a feed zone length (3) in the range from 0.1 SL and 0.45L, a taper angle, in the range from 0.5 degrees and 5.0 degrees and a compression ratio, CR, in the range from 2.0 and 5.0.

Abstract: A polyester composition containing: a) aluminum atoms; and b) alkaline earth atoms or alkali metal atoms or alkali compound residues such as lithium atoms; and c) particles comprising titanium, zirconium, vanadium, niobium, hafnium, tantalum, chromium, tungsten, molybdenum, iron, or nickel atoms or combinations thereof, where the particles improve the reheat rate of the polyester composition. The polyester polymer compositions may also contain phosphorus catalyst deactivators/stabilizers. The polyester compositions and the articles made from the compositions such as bottle preforms and stretch blow molded bottles have improved reheat rate while maintaining low haze, high L*, a b* below 3, and have low levels of acetaldehyde. In the process for making the polyester polymer, the polymer melt is polycondensed in the presence of a) and b), with the particles c) added in a melt phase process or added to the polymer in an injection molding machine or extruder. The polyester polymer composition can be made to high IV from the melt phase while avoiding solid state polymerization.
