Abstract
ESTA INVENCION SE REFIERE A UN PROCESO PARA HACER UN CAUCHO DE NITRILO QUE SE CARACTERIZA PORQUE ESENCIALMENTE NO TIENE GELES Y PORQUE ESTA SATURADA EN AL MENOS UN 90%. EL PROCESO CONSISTE EN HACER REACCIONAR UN POLIMERO ETILENICAMENTE INSATURADO A MODO LATEX, HIDRACINA Y UN OXIDANTE, SEGUIDO DE SU COAGULACION Y FILTRACION PARA SEPARAR EL CAUCHO REDUCIDO. EL PROCESO UTILIZA UNA MEZCLA DE REACCION QUE CONTIENE UNA ALTA RELACION MOLAR DE HIDRACINA RESPECTO AL POLIMERO INSATURADO.
