Abstract

LA ESPECIFICACION DESCRIBE UN METODO DE PREPARACION DE UN POLISILOXANO POR EXTENSION DE CADENA DE UN COMPUESTO DE SILICIO CON UNIDADES FINALES DE CADENA QUE INCLUYEN UN GRUPO HIDROXILO UNIDO CON SILICIO QUE COMPRENDE LA CONDENSACION DE LOS GRUPOS HIDROXILO UNIDOS CON SILICIO A UNA TEMPERATURA DE MENOS DE 50 (GRADOS) C EN PRESENCIA DE UN CATALIZADOR DE CONDENSACION ACIDO DE LA FORMULA RSO3H Y AGUA, A UNA EXTENSION DE MENOS DE 7 MOLES POR MOL DE CATALIZADOR DE CONDENSACION ACIDA. EL COMPUESTO DE SILICIO PUEDE COMPRENDER UN POLIDIMETILSILOXANO BLOQUEADO EN EL EXTREMO CON HIDROXILO, CON VISCOSIDAD A 25 (GRADOS) C EN EL INTEERVALO 30 A 100000 MM2/S, Y PUEDE SER POLIMERIZADO PARA PROPORCIONAR UN POLIMETILSILOXANO ALFA, OMEGA DIHIDROXI CON VISCOSIDAD EN EL INTERVALO DE 1000 MM2/S A 100000 MM2/S O MAS. EL CATALIZADOR PREFERIDO ES ACIDO DODECILBENCENOSULFONICO. PUEDE A/ADIRSE UN MATERIAL BASICO A LA MEZCLA DE REACCION PARA NEUTRALIZAR DICHO CATALIZADOR, P.E. CARBONATO DE CALCIO O MAGNESIO.
