Abstract
UN PROCESO PARA LA POLIMERIZACION DE UNA ALFA-OLEFINA LIQUIDA O UNA SOLUCION DE DOS O MAS ALFA-OLEFINAS Y, OPCIONALMENTE, UNA O MAS DIOLEFINAS. DONDE EL UNICO MEDIO DE PROCESO ES UNO O MAS DE DICHAS OLEFINAS LIQUIDAS , QUE COMPRENDE: (A) MEZCLAR LA ALFA-OLEFINA O LA SOLUCION CON UN MATERIAL INERTE QUE TIENE UN TAMAÑO DE PARTICULA PROMEDIO ENTRE 0,01 A 10 MICRONES EN UNA CANTIDAD DE NO MENOR DE 0,005% EN PESO DEL MATERIAL BASADO EN EL PESO TOTAL DE LA RESINA Y EL MATERIAL EN EL PRODUCTO FINAL; Y (B) CONTACTAR LA MEZCLA FORMADA EN (A) CON UN SISTEMA CATALIZADOR ADAPTADO PARA POLIMIZAR LAS OLEFINA EN LA MEZCLA A UNA TEMPERATURA Y PRESION SUFICIENTE PARA (I) DAR LAS CONDICIONES DE POLIMERIZACION; (II) MANTENER LA OLEFINA EN LA FASE LIQUIDA A TRAVES DE LA POLIMERIZACION; Y (III) MANTENER EL PRODUCTO POLIMERO EN SU FASE PASTOSA.
