Abstract: Multilayer plastic containers for food and beverage packaging which incorporate oxygen scavenging resins which selectively oxidize upon activation without giving off odorous fragments.

Abstract: Herein are disclosed polymeric metal salts useful in catalyzing oxygen scavenging by oxygen scavenging polymers. The polymeric metal salts comprise structure I: wherein R is selected from C1--C20 alkyl, C5-C20 cycloalkyl, C2-C40 branched alkyl, C2-C40 branched alkyl acid or diacid, C2-C12 alkenyl, C5-C12 cycloalkenyl, C2-C40 branched alkenyl, or C2-C40 branched alkenyl acid or diacid; and M is selected from manganese, iron, cobalt, nickel, copper, rhodium, or ruthenium. These polymeric metal salts are substantially non-extractable from a packaging article comprising the metal salts. Also disclosed are packaging articles comprising the polymeric metal salts, and methods of synthesizing the polymeric metal salts.

Abstract: Herein is disclosed multilayer packaging articles comprising an oxygen barrier layer comprising ethylene/vinyl alcohol copolymer (EVOH) (an “EVOH oxygen barrier layer”); an oxygen scavenging layer adjacent thereto, wherein the oxygen scavenging layer comprises a polymer comprising an ethylenic backbone and a cycloalkenyl group having structure I: 1

Abstract: Herein is disclosed an emulsion, comprising an oxygen scavenging polymer, water, and a surfactant. The emulsion can be formed by first forming an emulsion comprising at least one monomer, water, and the surfactant, and polymerizing the monomer. Once formed, the emulsion can be used to form an oxygen scavenging packaging article by coating at least one surface of the packaging article or contacting two surfaces of the packaging article with the emulsion, and evaporating water from the emulsion-coated or -contacted surface, to form a polymer coating.

Abstract: Herein is disclosed a blend of a neat oxygen scavenging polymer and a second polymer. The blend can be prepared by extrusion of a neat formulation of the oxygen scavenging polymer and the second polymer. Also disclosed are methods for preparing the neat formulation of the oxygen scavenging polymer, and packaging articles prepared from the blend. In addition, compositions comprising a branched oxygen scavenging polymer and a second polymer are disclosed, as well as packaging articles prepared from such compositions.

Abstract: A process for producing cyclohexene dimethanol or cyclohexane dimethanol compounds is provided. By controlling the rates of addition of certain reaction components and/or by controlling reaction solution temperatures at specific stages during synthesis, this invention provides a process for producing high purity cyclohexene dimethanol or cyclohexane dimethanol compounds without the need for solvent extraction and/or recrystallization procedures.

Abstract: Herein is disclosed a modified ethylene vinyl alcohol polymer (EVOH) comprising an oxygen scavenging functional group.

Abstract: Herein is disclosed an oxygen barrier composition comprising an oxygen barrier polymer and an oxygen scavenging polymer. The composition can be in the form of a physical blend or a cross-linked blend, and can further comprise a compatibilizer, a transesterification catalyst, or both. Preferably, the oxygen barrier polymer is poly(ethylene/vinyl alcohol) (EVOH), polyethylene terephthalate (PET), or polyamide other than MXD6. Preferably, the oxygen scavenging polymer comprises an ethylenic backbone and a pendant cyclic olefinic group, or the oxygen scavenging polymer is a polyamide derived at least in part from a xylene diamine-based monomer.
