ABSTRACT:
Segmented copolyesters/copolyethers in which the soft segment polyethers incorporate a thermally stable heterocyclic unit, e.g., hydantoin, are found to be useful as biomedical materials since the heterocyclic ring prevents crystallization of the soft segment, and further provides a chemically reactive site for incorporating other moieties to enhance certain properties, e.g., heparin for increasing the non-thrombogenicity of the biocompatible material.
