The present application discloses an implantable material and a synthesis method therefor and a prosthetic heart valve. The implantable material uses polyurethane, the molecular chain structure of polyurethane comprises a soft segment and a hard segment, and a functional branched chain is grafted onto the hard segment; the solubility parameter of the functional branched chain is 6-8. According to the present application, by introducing the functional branched chain into the hard segment, the compatibility between the hard segment and the soft segment is improved and the stress transfer points between the hard segment and the soft segment are increased, so that the prepared implantable polymer material has excellent mechanical properties. La présente demande divulgue un matériau implantable et son procédé de synthèse et une valve cardiaque prothétique. Le matériau implantable utilise du polyuréthane, la structure de chaîne moléculaire de polyuréthane comprend un segment souple et un segment dur, et une chaîne
