The polyester composition is (1) a copolymer containing a repeating unit A represented by the formula (I) and a repeating unit B represented by the formula (II) (where m is an integer of 2 to 10). And n is an integer from 2 to 8; p is an integer from 2 to 10; m, n and p are the same or different from each other) A first polyester selected from one or more; and (2) optionally a second polyester; wherein the polyester composition comprises at least two polyesters. The polyester composition is useful for a shape memory material, a 3D printed wire, a heat-shrinkable sleeve, a functional layer, a medical limb fixing device, a heat-shrinkable film, a nonwoven fabric, an elastic fiber, and the like.
