Abstract

An oxygen scavenger composition includes mer units that have at least one cycloalkenyl group or functionality and, further, has mer units de-rived from isophthalic acid or terephthalic acid or certain derivatives thereof. The oxygen scavenger composition has been found to act as an oxygen scavenger under both ambient and refrigeration conditions, to be compatible with conventional film forming packaging materials, to inhibit undesirable oligomer formation and oxidation by-product formation, and to be readily formable and processable using conventional film forming equipment. A film and laminated product having said oxygen scavenger composition are also disclosed.
