A novel aliphatic polycarbonate based polyurethane (PPCPU) was synthesized with various amounts of crosslinking agent and isocyanate.The prepolymer used was poly (propylene carbonate)
which was prepared by copolymerization of carbon dioxide and propylene oxide.PPCPU was characterized by FTIR

water absorption and mechanical property measurements.It is found that PPCPU had tensile strength as high as 20 MPa
water resistance better than conventional polyether polyure thane
and thermostability higher than the starting aliphatic polycarbonate.
