  • PROCEDE DE POLYMERISATION PAR VOIE CATALYTIQUE DE 1,4-DIOXANES-2,5-DIONES ET LES POLYMERES CORRESPONDANTS
    Publication number: 20120035341
    Abstract: A method for polymerizing 1,4-dioxane-2,5-diones in the presence of a generally protic initiator and at least one catalyst including at least one metal-free organic compound. The latter is a non-metal organic catalyst most often selected from among pyridines of which DMAP is a derivative, sulfonic acids, polycyclic tertiary amines, phosphazenes, thioureas, thioureas/amines, and guanidines. The invention also relates to polymers obtained by the method.
