  • Patent number: 9593239
    Abstract: This specification discloses a composition of a melt blend comprising a continuos polyester phase, a cobalt of manganese compound and a first scavenging compound wherein the first scavenging compound comprises at least one allylic group and at least one polar moiety and at least some of the first scavenging compound or the oligomer or the polymer comprising the first scavenging compound is not present in the continuous polyester phase. The partial insolubility is essential for oxygen scavenging and the solubility is essential for reducing haze. The composition is useful in preforms, container walls, and films for packaging.
    Type: Grant
    Filed: April 1, 2013
    Date of Patent: March 14, 2017
    Assignee: Biochemtex, S.p.A.
    Inventors: Ricardo Knudsen, D. Jeffrey Black, Gianluca Ferrari, Aaron Murray
  • Patent number: 9540507
    Abstract: A specially structured article is described which allows products made from the article to undergo a second heating without a dramatic color shift. This permits more recycled products from the material used to make the article.

  • Publication number: 20140145109
    Abstract: Butadiene, isoprene, and terpene based materials are soluble in polymer matrices such as polyethylene terephthalate when the butadiene, isoprene, or terpene compound also contains allylic carbons afterwith at least one polar moiety which is non-reactive to the matrix polymer. These compounds can be oxygen scavengers when in the presence of cobalt or manganese compounds and have been found to have substantially reduced haze in the final package.

  • Patent number: 7816008
    Abstract: This invention discloses a process and a necessary article to simultaneously thermally treat at least two thermoplastics. The process utilizes the necessary compartmentalized or zoned pellet construction wherein the major amount of each thermoplastic component is located within individual compartments or zones of the pellet such that the components of the reaction during thermal processing and/or reactions with compounds in the atmosphere such as oxygen are less than the reaction if the thermoplastics were homogeneously dispersed in the pellet. This invention allows the components of the multi-component pellets to be thermally treated together without significant degradation and/or stored in air or in the presence of oxygen without significant degradation.
