Abstract

PROCEDE PERMETTANT D'INTRODUIRE DES GROUPES SILANOL DANS UN POLYMERE DE FLUOROSILICONE DE MASSE MOLAIRE ELEVEE. IL CONSISTE: 1A FAIRE REAGIR DES ESPECES OU UN MELANGE D'ESPECES, A. D'UN CYCLOPOLYSILOXANE DE FORMULE: (R RSIO)OU R ET R SONT CHOISIS DANS LE GROUPE COMPRENANT LES RADICAUX HYDROCARBONES MONOVALENTS ET LES RADICAUX HYDROCARBONES MONOVALENTS FLUORES, ET DANS LAQUELLE, S'IL Y A UN MELANGE D'ESPECES DE CYCLOPOLYSILOXANE, DOIT ETRE PRESENT UN CYCLOPOLYSILOXANE AVEC DES RADICAUX HYDROCARBONES FLUORO-SUBSTITUES, T EST EGAL A 3, B. UN LIMITEUR DE CHAINE DE FORMULE: (CF DESSIN DANS BOPI) OU R ET R SONT CHOISIS DANS LE GROUPE COMPRENANT LES RADICAUX HYDROCARBONES MONOVALENTS ET LES RADICAUX HYDROCARBONES MONOVALENTS HALOGENES, S EST UN NOMBRE ENTIER VARIANT DE 2 A 50, ET C.UN CATALYSEUR DE POLYMERISATION BASIQUE, ET 2A NEUTRALISER LE CATALYSEUR DE POLYMERISATION BASIQUE. APPLICATION AUX ELASTOMERES DE SILICONE.PROCESS FOR INTRODUCING SILANOL GROUPS INTO A FLUOROSILICONE POLYMER OF HIGH MOLAR MASS. IT CONSISTS OF: 1A REACTING SPECIES OR A MIXTURE OF SPECIES, A. A CYCLOPOLYSILOXANE OF FORMULA: (R RSIO) OR R AND R ARE CHOSEN FROM THE GROUP INCLUDING MONOVALENT HYDROCARBON RADICALS AND MONO-CARBON HYDROCARBON RADICALS AND MONO-CARBON, AND MONDROCARBON RADICALS, AND FLONES, AND IN WHICH, IF THERE IS A MIXTURE OF SPECIES OF CYCLOPOLYSILOXANE, MUST BE PRESENT A CYCLOPOLYSILOXANE WITH FLUORO-SUBSTITUTED HYDROCARBON RADICALS, T IS EQUAL TO 3, B. A CHAIN LIMITER OF FORMULA: (CF DRAWING IN BOPI) WHERE R AND R ARE CHOSEN FROM THE GROUP CONSISTING OF SINGLE-VALENT HYDROCARBON RADICALS AND SINGLE-HALOGENOUS SINGLE-CARBON HYDROCARBON RADICALS, S IS AN ENTIRE NUMBER VARIING FROM 2 TO 50, AND C. A BASIC POLYMERIZATION CATALYZER FROM NE POLYMERIZATION POLYMERIZATION, AND 2A POLYMERIZATION BASIC. APPLICATION TO SILICONE ELASTOMERS.
