Claim Text:
1. A composition comprising: a) a polyester base polymer; b) at least one oligomeric, oxidizable poly(alkylene ether) glycol-α,ω-diester having the formula wherein, R is a substituted or unsubstituted alkylene chain having from 2 to 10 carbon atoms; R′ and R″ are each independently an alkyl sulfonic acid group or a metal salt thereof, an aryl sulfonic acid group or a metal salt thereof, an alkyl group having from 1 to 18 carbon atoms, or an aromatic group having from 6 to 18 carbon atoms; and n is from 4 to 100; and c) at least one transition metal in a positive oxidation state, said metal being present in the composition in an amount of from about 10 to about 400 ppm, wherein the at least one oligomeric, oxidizable poly(alkylene ether) glycol-α,ω-diester is present in an amount of from about 0.10 to about 10 weight percent of the composition, wherein at least one of R′ and R″ is either (1) an alkyl sulfonic acid group or a metal salt thereof or (2) an aryl sulfonic acid group or a metal salt thereof.
