Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester composition with excellent strength, toughness, clarity, chemical resistance, and UV resistance that is useful for an oriented, shaped article.SOLUTION: The polyester composition comprises: (i) 20-80 wt.%, based on the total alicyclic polyester comprising 98-100 mol%, based on the total mol% of diacid residues, of residues of one or more of diacid selected from 1,3-cyclohexanedicarboxylic acid and 1,4-cyclohexanedicarboxylic acid; and 70-100 mol%, based on the total mol% of diol residues, of residues of one or more diol selected from 1,3-cyclohexanedimethanol, 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and 1,4-cyclohexanedimethanol; and (ii) 20-80 wt.% of a polyester elastomer; wherein the composition at 25°C has a storage elastic modulus of at least 0.3 GPa and a tan δ of at least 0.02.
