Development of Water-bone Aliphatic Polycarbonate Polyurethane

Water-bone polycarbonate polyurethane as a novel polyurethane material,comparing with poly(ester) urethane,owns more advantages as better mechanical properties,water resistantce and biological compatibility.The reaction kinetic of the polycarbonate polyurethane is the non-catalytic second order one,and the properties of polycarbonate polyurethane are influced by the structure of the soft and hard segments,the length of the soft segment,the crosslinking degrees and the mathods of the synthesis.
