Abstract

LE PROCEDE CONSISTE A AJOUTER A UN HYDROLYSAT DE DIORGANO-DIHALOGENOSILANE OU A UN MELANGE DE POLYSILOXANES CYCLIQUES, SERVANT DE MATIERE PREMIERE POUR LA REACTION DE CRAQUAGE, UNE QUANTITE EFFICACE D'HYDROXYDE DE METAL ALCALIN ET UNE QUANTITE EFFICACE D'UN ALCOOL ALIPHATIQUE DE MASSE MOLAIRE ELEVEE ET A CHAUFFER L'ENSEMBLE A UNE TEMPERATURE SUPERIEURE A 100C. ON DISTILLE LE TRISILOXANE CYCLIQUE AU FUR ET A MESURE DE SA FORMATION. LE PRODUIT OBTENU TROUVE SON APPLICATION DANS LA FABRICATION DE COMPOSITIONS DE CAOUTCHOUC SILICONE DURCISSABLES A LA CHALEUR OU A LA TEMPERATURE AMBIANTE.
