Abstract

UN METODO PARA PRODUCIR UN POLIDIORGANOSILOXANO EXENTO DE GRUPOS HIDROXILO. SE PUEDE PREPARAR UNA GOMA DE POLIDIORGANOSILOXANO, DEL TIPO QUE SE PRODUCE POR POLIMERIZACION DE ORGANOCICLOHEXANOS CATALIZADA CON METALES ALCALINOS, QUE NO CONTIENE GRUPOS HIDROXILO, MEZCLANDO LA GOMA CON UN COMPONENTE FOSFORICO DE NATURALEZA ACIDA O PRODUCTOR DE ACIDO Y UN COMPONENTE TRIALQUILSILILACETAMIDICO, DEJANDO QUE LA MEZCLA REACCIONE HASTA ELIMINAR LOS GRUPOS HIDROXILO Y, DESPUES, DESVOLATILIZANDO LA GOMA. EL CONTENIDO EN HIDROXILOS SE PUEDE ELIMINAR SIN OCASIONAR CAMBIOS CONSIDERABLES EN EL PESO MOLECULAR DE LA GOMA Y PRODUCIENDO UNA GOMA QUE ES ESTABLE AL CALOR A TEMPERATURAS DE UNOS 250GC SIN LA ADICION DE ESTABILIZANTES CALORIFICOS.
