Abstract

Se describe un proceso para polimerizar una o más Ó-olefinas de hasta 20átomos de carbono, el cual comprende poner en contacto una o más Óolefinas bajo condiciones de polimerización con un sistema catalizador quecomprende: (a) un componente pro-catalizador que contiene magnesio quecontiene titanio , en el componente se obtiene poniendo en contacto uncompuesto de magnesio de la fórmula MgR'R", en la que R'y R" son,independientemente, un grupo alcoxido, un grupo ariloxido o halógeno, conun compuesto de titanio tetravalente halogenado, en presencia de un éterde ácido policarboxilico donador de electrones con o sin unhalohidrocarburo, (b) un componente co-ca-talizador de órgano-aluminio y(c) un agente para el control de la selectividad organosilano representadopor la fórmula general: ( Ver Fórmula I) en la R1 es un grupo alquilo de13 a 30 átomos de carbono, un grupo alcarilo de 16 a 36 átomos de carbono;R2 y R3 son, independientemente, metilo o un grupo alquilo de 13 a 30átomos de carbono o un grupo hidrocarbiloxi de 1 a 6 átomos de carbono; yR4 es un grupo hidrocarbiloxi de 1 a 6 átomos de carbono. El proceso deuna productividad de catalizador elevada que produce productos poliméricosque tienen amplia distribución de peso molecular, mientras que retienensus propiedades con bajo contenido de oligómero.
