摘要： Disclosed are stabilized polyester compositions having significantly improved weatherability. These polyesters consist of copolyesterethers derived from a dicarboxylic acid component comprising about 80-100 mole % 1,4-cyclohexanedicarboxylic acid having a trans isomer content of at least 70% and about 0-20 mole % of a second dicarboxylic acid and a glycol component comprising about 70-95 mole % 1,4-cyclohexanedimethanol and about 5-30 mole % of a polyalkylene ether glycol having a molecular weight of about 600 to about 3000. The copolyesterether compositions further comprise a stabilizing effective amount of the combination of (1) at least one hindered phenolic antioxidant, (2) at least one ultraviolet light stabilizing compound compatible with said copolyesterether and (3) at least one hindered amine light stabilizing compound having the formulae ##STR1## the groups shown as R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are each independently selected from various substituents.
