| 摘要 |
A polymer, particularly a biomedical polymer for the fabrication of medical and surgical devices and for use as a coating, is described. The polymer is derived from the reaction product of one or more lactone monomers and castor oil preferably: (a) .epsilon.-caprolactone, trimethylene carbonate or an ether lactone; (b) castor oil; and (c) glycolide, lactide or 1,4-dioxanone. The preferred polymer is derived from .epsilon.-caprolactone, castor oil, and glycolide. The polymer in preferred embodiments is ideally suited for use as a coating for a surgical suture, particularly an absorbable, braided multifilament suture and surgical needles. For this application, glycerol is advantageously added to the reactive monomer mix from which the polymer is derived.
