INTRODUCTIONrnAmong the biomedical applications of synthetic polymers, the development ofblood-handling equipment has been one of the most investigated areas in the past twodecades. Polyurethanes have been used as blood-contacting biomaterials due to theirexcellent mechanical properties and acceptable blood compatibility which is relativelybetter than most of other synthetic polymer materials.rn
