Abstract:
A composition comprising: a polyester base polymer; a blend of two distinct polyether-based oxygen scavenging additives, OS1 and OS2, wherein each of OS1 and OS2 is selected from the group consisting of a polyether diol, an ester end-capped derivative of a polyether diol, a polyether-polyester block copolymer, and an ether end-capped derivative of a polyetherdiol, wherein OS1 has a molecular weight of from 10,000 to 100,000 and OS2 has a molecular weight of from 200 to 5,000; and a transition metal catalyst.
