POLYESTER CONTAINER WITH ENHANCED GAS BARRIER AND METHOD

摘要

A polyester container with enhanced gas barrier properties comprises a polyester composition having an IV of 0.65 dL/g to 1.0 dL/g and comprising a polyester and a reactive organic gas barrier enhancing additive. The polyester is made using at least one first polycondensation catalyst selected from the group consisting of metals in Groups 3, 4, 13, and 14 of the Periodic Table and comprises a catalyst residue remaining in the polyester from formation of the polyester. The catalyst residue comprises at least a portion of the at least one first polycondensation catalyst.
