Abstract

OLEFINAS DE LA FORMULA SE POLIMERIZAN EN PRESENCIA DE UN CATALIZADOR CONSISTENTE EN UN ALUMINOXANO Y UN METALOCENO DE LA FORMULA (I) O (II). (R ELEVADO 1, R (AL CUADRADO) = HALOGENO O RESTOS DE HIDROCARBUROS; R ELEVADO 3, R ELEVADO 4 = RESTOS DE HIDROCARBUROS, QUE PUEDEN FORMAR CON M ELEVADO 1 UNA ESTRUCTURA SANDWICH; R ELEVADO 5 = PUENTE DE UNO O VARIOS MIEMBROS). COMO MEDIO DE SOLUCION O SUSPENSION SIRVE UN DISOLVENTE POLAR Y APROTICO , ESPECIALMENTE UN HIDROCARBURO HALOGENADO CON UNA CONSTANTE ESTATICA DE DIELECTRICIDAD MAYOR QUE 3 A 20 C. SE OBTIENE UN GRAN NUMERO DE POLIMEROS CON UNA MASA MOLECULAR MUY ALTA.
