Title
(EN) THIOURETHANE POLYMERS, METHOD OF SYNTHESIS THEREOF AND USE IN FUSED FILAMENT FABRICATION PRINTING
(FR) POLYMÈRES DE THIOURÉTHANE, PROCÉDÉ DE SYNTHÈSE ET D'UTILISATION DE CES POLYMÈRES DANS L'IMPRESSION PAR DÉPÔT DE FIL FONDU
Abstract
(EN)
A thermoplastic thiourethane polymer comprising a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. The first type of monomer includes two or more thiol functional groups and the type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anhydrous aprotic solvent-dissolved anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7.
(FR)
L'invention concerne un polymère de thiouréthane thermoplastique comprenant une chaîne séquentielle d'un premier type de monomère lié par covalence à un deuxième type de monomère, par l'intermédiaire de liaisons thiouréthane. Le premier type de monomère comprend au moins deux groupes fonctionnels thiol et le deuxième type de monomère comprend au moins deux groupes fonctionnels isocyanate. Les premier et deuxième types de monomères sont polymérisés ensemble dans une réaction de polymérisation anionique par étapes à dissolution dans un solvant aprotique anhydre, qui est catalysée par une base non nucléophile présentant un pKa supérieur à 7.
