ABSTRACT:
Copolyetheresters are stabilized against oxidative degradation due to exposure to heat and light by incorporating into the polymer effective concentrations of a phenolic antioxidant and copolymerized hindered amine photostabilizer units having the formula ##STR1## wherein A is ethylene and/or propylene, X is a divalent hydrocarbon radical of 2 to 18 carbon atoms and (n + m) equals 5 to 40, said photostabilizer units being connected to ester units in the copolyetherester through ester linkages.
