| abstract |
A film, laminated product, and other packaging materials are disclosed, each including an oxygen scavenger composition comprising a condensation polymer and a transition metal salt, compound or complex, wherein said polymer comprises mer units derived from a substituted alicyclic compound having non-aromatic ethylenic functionality (A), mer units including an ionomeric group (B), and mer units of a di- or polyfunctional hydrocarbon compound (C), wherein said condensation polymer comprises from 40 to 60 molar percent (A), from 0.25 to 20 molar percent (B), and from 40 to 60 molar percent (C). Certain oxygen scavenger compositions have 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. |
