| abstract |
The present invention provides a biocompatible and biodegradable elastomer, comprising a hard segment and a soft segment. The hard segment is formed by reacting diisocyanate and a chain extender; and the soft segment is comprising a biodegradable oligomer diol, wherein the biodegradable oligomer diol is selected from the group consisting of polycaprolactone diol, polyethylene butylene adipate diol (PEBA diol), poly-L-lactic acid diol (PLLA diol), polylactic acid diol and any combination thereof. The biocompatible and biodegradable elastomer of present invention can be used to produce vascular graft, cell carrier, drug carrier or gene carrier. |
