Abstract

SE PRESENTAN NUEVOS PROCESOS DE LECHO FLUIDO, DE FASE DE GAS PARA PRODUCIR POLIMEROS SE ETILENO QUE TENGAN UNA PROCESABILIDAD MEJORADA. PUEDEN USARSE REACTORES MULTIPLES EN SERIE O EN PARALELO PARA PRODUCIR POLIMEROS MEZCLADOS IN SITU. CADA REACTOR PUEDE TENER SEPARADAMENTE UN CATALIZADOR DE GEOMETRIA CONSTREÑIDA O UN CATALIZADOR ZIEGLER-NATTA CONVENCIONAL SEGUN SE NECESITE PARA OBTENER EL POLIMERO MEZCLADO IN SITU CON LAS PROPIEDADES DESEADAS TANTO TIEMPO COMO HAYA UN CATALIZADOR DE GEOMETRIA CONSTREÑIDA EN AL MENOS UN REACTOR. DE ACUERDO CON ESTA INVENCION PUEDEN PRODUCIRSE POLIMEROS DE OLEFINA QUE TENGA UNA BAJA SUSCEPTIBILIDAD A LA FRACTURA POR FUSION INCLUSO BAJO CONDICIONES DE FUERZAS DE CORTE ALTAS.
