Abstract

EN UNA PRIMERA ETAPA DE ESTE PROCESO, SE PREPARA UN LATEX EN EMULSION ACUOSA, EN PRESENCIA DE AL MENOS UN AGENTE TENSIOACTIVO IONICO, DE AL MENOS UN MONOMERO ETILENICAMENTE NO SATURADO; A CONTINUACION, EN UNA SEGUNDA ETAPA, SE AÑADE AL LATEX ASI OBTENIDO AL MENOS UN MONOMERO VINILICO, INSOLUBLE EN EL AGUA Y SE NEUTRALIZA LAS CARGAS IONICAS LLEVADAS POR DICHO LATEX, AÑADIENDO A LA MEZCLA DE LATEX Y DE MONOMERO, AL MENOS UN AGENTE DE TRANSFERENCIA LLEVANDO CARGAS IONICAS OPUESTAS A LAS DE TENSIOACTIVO UTILIZADO EN LA PRIMERA ETAPA, PARA REALIZAR LA TRANSFERENCIA DE LAS PARTICULAS DEL LATEX EN EL MONOMERO VINILICO; A CONTINUACION EN UNA TERCERA ETAPA, SE SEPARA DE LA FASE ACUOSA LA FASE ORGANICA COMPUESTA POR EL LATEX Y EL MONOMERO VINILICO; Y EN UNA CUARTA ETAPA, SE EFECTUA LA POLIMERIZACION EN MASA DE LA FASE ORGANICA DE MANERA A OBTENER LA PLACA COLADA TRAS ENFRIAMIENTO Y DESMOLDEO.
