Abstract:
The present application relates to novel polyester-ether compositions and their use as oxygen scavenging materials in polyester resins.

Claim (Index 14):
A masterbatch for use in preparing an article, preform or container comprising:\n a) copolyester-ether,\n wherein the copolyester-ether comprises one or more polyester segments and one or more polyether segments, wherein the one or more polyether segments are present in an amount of about 5 to about 95 wt.-% of the copolyester-ether; and \n b) a monomeric, oligomeric or polymeric hindered amine light stabilizer (HALS) in an amount of 100-30,000 ppm, on basis of the weight of the stabilizer in the total composition, wherein the HALS is represented by the formula (I) or a mixture of compounds of formula (I), wherein each R 1  independently represents C 1 -C 4  alkyl, R 2  represents H, C 1 -C 4  alkyl, OH, O\u2014C 1 -C 4  alkyl, or a further part of an oligomeric or polymeric HALS, and R 3  represents a further part of a monomeric, oligomeric or polymeric HALS; wherein the masterbatch does not contain inorganic pigments in an amount of above 0.6 wt.-% of the total masterbatch and wherein the masterbatch does not contain carbon black in an amount of above 1.2 wt.-% of the total masterbatch.
