Its production process by esterification or transesterification of an oxygen scavenging for ethylene composition and reaction extruder in

摘要

(57) a method of transesterification of a polymer having pendant ester moieties and [Abstract] polyethylene backbone, is contacted with a transesterification compound in a reaction extruder in a melt of the polymer, polymer transesterification receive, the method alcoholysis kept free is disclosed. Polymers are transesterified, having pendant ester moieties with different number (or) type and unreacted polymer. In one embodiment, the method also includes adding a transition metal salt in an amount effective to promote oxygen scavenging. As yet another aspect, the method comprises irradiating with actinic radiation a polymer transesterified and shorten the induction period before oxygen scavenging commences. Composition comprising a component having a terminal portion is also disclosed or suspension having a benzyl group and ethylenic backbone. The present invention and its embodiments are also polyethylene-based oxygen-scavenging composition for a novel consisting of transition metal salt components and having an end portion or pendant with a benzyl group and polyethylene-based backbone. A method of producing a composition thereof, are also disclosed compositions and methods and using an ethylene composition.
