Реферат: Se describe una composicion de catalizador que comprende un complejo de zirconio de un ariloxiéter polivalente y un alumoxano, procesos de polimerizacion que utilizan la misma, especialmente la polimerizacion en solucion continua de etileno y una o más alfa-olefinas o diolefinas de 3 a 30 átomos de carbono para preparar copolímeros que tienen un contenido reducido del subproducto del co- catalizador. A catalyst composition is described comprising a zirconium complex of a polyvalent aryloxyether and an alumoxane, polymerization processes using the same, especially the polymerization in continuous solution of ethylene and one or more alpha-olefins or diolefins of 3 to 30 atoms carbon to prepare copolymers having a reduced co-catalyst by-product content.
