Abstract

L'INVENTION CONCERNE LA VULCANISATION A LA PRESSE (AU MOULE) D'ELASTOMERES FLUORES QUI SONT DES COPOLYMERES DU FLUORURE DE VINYLIDENE AVEC UN OU PLUSIEURS AUTRES MONOMERES FLUORES INSATURES, PAR RETICULATION AVEC UN COMPOSE POLYHYDROXYLIQUE AROMATIQUE EN PRESENCE D'UN ACCELERATEUR ET EN MILIEU FAIBLEMENT BASIQUE. SELON CETTE INVENTION, UNE PARTIE AU MOINS DES HYDROXYLES DU COMPOSE POLYHYDROXYLIQUE SONT BLOQUES PAR TRANSFORMATION EN GROUPES ACETAL OU THIOACETAL. A LA TEMPERATURE DE VULCANISATION A LA PRESSE CERTAINS DES GROUPES ACETAL OU THIOACETAL SONT DECOMPOSES ET LES HYDROXYLES LIBRES SE REFORMENT, CE QUI PERMET LA RETICULATION, LES AUTRES GROUPES ACETAL OU THIOACETAL ETANT DECOMPOSES AU COURS D'UNE VULCANISATION COMPLEMENTAIRE PAR CHAUFFAGE A UNE TEMPERATURE SUPERIEURE, CE QUI ASSURE UNE VULCANISATION TOTALE. LES COMPOSITIONS VULCANISABLES SELON L'INVENTION COULENT BIEN DANS LES MOULES A LA TEMPERATURE DE VULCANISATION; LES PRODUITS VULCANISES ONT UN EXCELLENT ALLONGEMENT EN TRACTION A CHAUD, CE QUI PERMET DES DEMOULAGES FACILES SANS DECHIRURES, ET PAR SUITE DE LEUR FAIBLE ETAT DE VULCANISATION A LA SORTIE DU MOULE, ILS PEUVENT ETRE FACILEMENT RECYCLES A LA FABRICATION APRES MELANGE AVEC L'ELASTOMERE FLUORE VIERGE, CE QUI SUPPRIME OU REDUIT LES DECHETS OU REBUTS DE PRODUITS.
