Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIOLEFINAS PULVERIFORMES POR POLIMERIZACION CATALITICA EN FASE GASEOSA DE ETILENO O SU COPOLIMERIZACION CON PROPILENO Y/O BULITENO-1. LA REACCON DE POLIMERIZACION SE EFECTUA A PRESIONES DE 10 A 100 BARES, A TEMPERATURAS COMPRENDIDAS ENTRE 50 Y 110C, Y EN PRESENCIA DE UN CATALIZADORZIEGLER, QUE SE OBTIENE MEZCLANDO LOS SIGUIENTES COMPONENTES: UN COMPONENTE DE ALUMINIO, EN LA PROPORCION MOLAR DE 1:3 A 1:1 DE V:AL; XEROGEL DE SILICE EN PARTICULAS FINAS; UNA POLIOLEFINA PULVERIFORME CON UN DIAMETRO MEDIO DE PARTICULAS DE HASTA 1000 UM; UN COMPUESTO ORGANOALUMINICO DE FORMULA RNA1X3-N, EN LA QUE R ES UN RADICAL ALQUILICO C2-20, X ES UN ATOMO DE HALOGENO Y N VALE 1-3. ESTAS POLIOLEFINAS TIENEN APLICACLIONES PARA LA ELABORACION DE PIEZAS PERFILADAS.
