A precursor of The Catalyst, a catalyst precursor composition obtained by such a procedure for preparing olefin Polymer Composition and a mediantedicha olefin Polymer,Particularly Ethylene, well prepared.

摘要

A precursor of formula (I) catalyst is provided,Among them, l is a cyclopropene; W, x, y and Z are independent hydrogen, non stick carbon compounds or silicon groups containing 1 to 20 carbon atoms, which can be connected with L through a bridge group consisting of at least two atoms of the group;The condition is that x, y, and Z are a stable load group selected from a group of three members of the group,Arilo group, isoaromatics group, unsaturated Party B hydrocarbon group, unsaturated Party B hydrocarbon group, node group and aromatic organic metal part. When the precursor of the catalyst is combined with a compound composed of iiib-viii metals or lant series metals in the periodic table of elements and an active cocaine catalyst, it is helpful for the polymerization of oil.
