Abstract
A novel bioabsorbable suture, poly(glycolide caprolactone) (PGLCL) copolymer, was synthesized by second step polymerization. The effect of the reaction parameters on the inherent viscosity of the PGLCL prepolymer was examined. The chemical structure of the copolymer was characterized by 1H nuclear magnetic resonance (NMR) and 13C NMR spectroscopy. The thermal properties of the copolymer were examined by differential scanning calorimetry and thermogravimetric analysis. Both the straight strength and knot strength of the PGLCL copolymer monofilament in vivo decreased significantly with increasing implant time. The organism resolvability tests confirmed that the PGLCL copolymer monofilament suture had been absorbed within 91 days with recovery from the inflammatory response. The biocompatibility tests indicated that all items had passed.
