Abstract

PROCEDIMIENTO PARA LA FABRICACION DE POLIMEROS OLEFINICOS EMPLEANDO CATALIZADORES QUE PERMANECEN EN EL POLIMERO Y QUE SON DESACTIVADOS ANTES DE TERMINAR LA POLIMERIZACION. CONSISTE EN SOMETER A REACCION DE POLIMERIZACION AL MENOS UNA A-OLEFINA, EN PRESENCIA DE UN CATALIZADOR QUE CONTIENE HALOGENO, A UNA TEMPERATURA COMPRENDIDA ENTRE 50 Y 300 GRADOS Y A UNA PRESION COMPRENDIDA ENTRE 150 PSIG Y 5.000 PSIG, Y EN DESACTIVAR EL CATALIZADOR MEDIANTE UNA COMPOSICION REPRESENTADA POR LA FORMULA GENERAL (I), EN LA QUE A Y B SON ELEMENTOS METALICOS CON VALENCIAS COMPRENDIDAS ENTRE 1 Y 2 O ENTRE 2 Y 3; X ES CERO O 1; C ES UN ANION CON VALENCIA 1, 2 O 3; Y N ES CERO O 1, QUE SE INYECTA EN CANTIDAD SUFICIENTE EN LA MEZCLA DE REACCION.
