  • Polyester container with enhanced gas barrier and method
    Patent number: 8545952
    Abstract: A polyester container with enhanced gas barrier properties includes a polyester composition having an IV of 0.65 dL/g to 1.0 dL/g and including a polyester and a reactive organic gas barrier enhancing additive. The polyester is made using at least one first polycondensation catalyst, non-limiting examples of which include metals in Groups 3, 4, 13, and 14 of the Periodic Table and includes a catalyst residue remaining in the polyester from formation of the polyester. The catalyst residue includes at least a portion of the at least one first polycondensation catalyst.

  • Pressurized tooling for injection molding and method of using
    Patent number: 7790077
    Abstract: The present invention relates to an apparatus and process for injection molding polymer articles that reduces deposition of additives on the apparatus. Specifically, pressurizing of the mold cavity with a pressurized gas reduces the deposition of low molecular weight additives on the apparatus. Embodiments of the invention also include an apparatus for injection molding polymer articles comprising at least one pressurized gas inlet for introducing a pressurized gas into the mold cavity.
