摘要

Bis - arilariloxi catalytic system for the production of ethylene homopolymers or copolymers of ethylene with alpha olefins.The present invention relates to a catalyst system for the production of homopolimeros bisarilariloxi or copolimeros ethylene EC - olefins.Which has a high catalytic activity; in particular,It relates to a transition metal catalyst comprising a transition metal of group IV as a central metal.A derivative of cyclopentadiene around the metal center and two ligands arilu00f4xido replaced with derivatives of arila in ortho positions, the ligands are not connected to each other.As well as a catalyst system comprising said catalyst and a co catalyst of aluminoxano or a co catalyst of compound of boron and a method for the production of homopolymers or glass.Lu00edmeros terephthalate with high molecular weight with CT olefins using the same.
