Abstract
PROCEDIMIENTO DE POLIMERIZACION DE ETILENO Y/O COPOLIMERIZACION DE ETILENO CON ALFA-OLEFINAS A PRESION Y TEMPERATURA ELEVADAS, EN PRESENCIA DE CATALIZADORES DE ZIEGLER. LA POLIMERIZACION SE PUEDE LLEVAR A CABO A PRESIONES DE HASTA 3.000 BAR Y TEMPERATURAS DE HASTA 350JC, EMPLEANDO UN SISTEMA ESTALITICO FORMADO POR UN ACTIVADOR A BASE DE ALQUILALUMINIOS O ALQUILSILOXALANOS Y UN COMPUESTO DE FORMULA (TICL3)(ALCL3)A (MGCL2)B(E)C, EN LA QUE 0 A 1, 1 B 10 Y 0,01 C 1, SIENDO E UN DONADOR DE ELECTRONES (ALCOHOLES, ETERES, CETONAS, ALDEHIDOS, ESTERES O ACIDOS CARBOXILICOS). ESTE CATALIZADOR SE PUEDE OBTENER POR MOLIENDA EN DOS ETAPAS, EN LA PRIMERA SE EFECTUA LA MOLIENDA DEL MGCL2 CON EL COMPUESTO (E) Y EN LA SEGUNDA LA COMOLIENDA DEL PRODUCTO ASI OBTENIDO CON (TICL3) Y (ALCL3).
