Methods and compositions for improved oxygen scavenging

摘要

A composition capable of scavenging oxygen composed of (i) a copolymer having long chain branches comprising units derived from monomers of ethylene and at least one vinyl unsaturated alicyclic monomer; (ii) a transition metal catalyst; (iii) preferably, with a photoinitiator; and (iv) optionally, a polymeric diluent.
