Polymethacrylates.Material Selection For Medical Applications:Requirements For Several Kinds of Medical Applications
Chapitre d'ouvrage scientifique
Résumé
This chapter reviews several cases of methacrylate-based polymers used for medical applications. The main chemicals and fillers used for elaborating biomaterials are presented, together with the main synthesis reactions. Their properties are recalled and discussed using the well-established structure-properties relationships of polymer physicochemistry. Last, the main degradation mechanisms are recalled, together with their consequences on the engineering properties of polymethacrylates, in order to predict the long-term in vivo behavior of such complex materials.

Article dans une revue avec comité de lecturePOMES, Benjamin; DERUE, Isabelle; LUCAS, Albert; NGUYEN, Jean-François; RICHAUD, Emmanuel (Elsevier, 2018)This work explores the process of water ageing of high-temperature high-pressure polymerized urethane dimethacrylate (UDMA) networks. UDMA samples polymerized under several pressures (0.1–300 MPa) and differing by the ...
