Abstract

LA INVENCION SE REFIERE A UN METODO PARA PREVENIR OBTURACIONES EN REACTORES DE POLIMERIZACION, EN PARTICULAR EN REACTORES DE BUCLE, EN LOS QUE SE POLIMERIZAN O COPOLIMERIZAN ALFA-OLEFINAS EN FORMA DE PARTICULAS EN PRESENCIA DE CATALIZADORES. SE AÑADE UNA MEZCLA DE COPOLIMEROS DE ALFA - OLEFIN - ACRILONITRILO Y POLIAMINAS POLIMERICAS EN UN REACTOR PARA PREVENIR LA OBTURACION DEL REACTOR.
