| titleOfInvention | An oxygen scavenging polyethylene terephthalate based polymer |
| abstract | The present invention improves the effectiveness of the oxygen scavengingncomposition and maintains an excellent balance in the color properties of the polymer.nThe present invention relates to an improved oxygen scavenging PET basedncopolymer comprising from about 10 to about 120 ppm cobalt based on the PETnpolymer, and from about 15 to about 150 ppm zinc based on the PET polymer. Thenpresent invention also comprises a process for preparing a PET based oxygennscavenging copolymer, comprising the steps of:n a) polymerizing monomers to produce a PET based polymer; b) adding Zn, Co, and an oxygen scavenging compound during said polymerizingnstep; c) copolymerizing said oxygen scavenging compound with said PET basednpolymer to form a copolymer; and optionally d) extruding said copolymer. n The present invention also comprises an oxygen barrier container having one or morenlayers of a PET based oxygen scavenging copolymer having from about 10 to aboutn120 ppm Co based on said PET polymer, and from about 15 to about 150 ppm Znnbased on the PET polymer; and an oxygen scavenging compound wherein said Conand said Zn are catalysts for said oxygen scavenging compound. |
