| abstract |
The present invention is directed to an oxygen scavenger composition comprising a mixture of (i) a polyester polymer composed of polymer segments containing cycloalkenyl group or functionality; and (ii) an ester type polymer selected from (a)a polyester having a high content of alkylene groups; (b) a polylactone; and (c) a polyvinylacetate having at least about 50 weight percent vinyl acetate mer units therein. The present polymer composition has been found to act as an oxygen scavenger agent under both ambient and refrigerated conditions, to be compatible with conventional film forming packaging materials, to provide compositions exhibiting low tack, and to be capable of being readily processed using conventional film forming equipment. |
