The invention discloses a polymer material for an anti-calcification heart valve, which comprises the following steps: preparation of (mono) condensation monomer of double-end hydroxyl benzophenone, (di) preparation of chloro citric acid derivative, (tri) ionization condensation polymer, (tetra) ion exchange. The preparation method of the polymer material for the heart valve is simple and easy to implement, and the preparation cost is low; the prepared polymer material for the heart valve has the advantages of good tissue compatibility, high biological stability, excellent antithrombotic and calcification-resistant performances and mechanical performance similar to that of a human valve. |
