Abstract:
Described herein are oxygen scavengers, oxygen scavenging polymeric compositions, and oxygen scavenging articles. The polymeric compositions comprising the oxygen scavengers may have utility in packaging, sealing, wrapping, and storing oxygen-sensitive substances, e.g., to preserve freshness of foods, beverages, and the like.

Claim (Index 1):
An article having at least one wall, the at least one wall comprising a polyester host polymer made by reacting at least one acid selected from the group consisting of terephthalic acid and isophthalic acid or their dimethyl esters with at least one glycol selected from the group consisting of ethylene glycol, diethylene glycol, 1,4 butane diol and 1,3 butane diol, and 1,4-cyclohexanedimethanol (CHDM); and\n an oxygen scavenging composition comprising one or more oxygen scavengers having formula (II-2), (II-2\u2032), or (II-2\u2033): wherein R 12  and R 13  are independently H, or any saturated or unsaturated, aliphatic or aryl, linear or branched, cyclic or acyclic, unsubstituted or substituted hydrocarbyl group and n=1, 2, 3, 4, or 5, wherein the article is selected from the group consisting of a bottle and a preform.
