1. An absorbable aliphatic polyester copolymer comprising:
a polyaxial core, with at least three axes, including a pre-polymer; wherein the at least three axes comprise polymeric chains; at least one flexible linking segment; and at least one polymeric end graft comprising repeat units derived from at least one cyclic monomer capable of crystallization, the at least one polymeric end graft attached to each of the at least three axes. |
