Abstract:
     A metallocene catalyst for polymerizing olefine features that the reaction resultants of the indene, fluorene or its substituted derivative, cyclopentadiene or substituted cyclopentadiene with zironium, titanium, or hafnium tertra-chloride are used as its active components to catalyze ethylene or copolymerize ethlene with alpha-olefine. The obtained resin has wide distribution peak of molecular weights (0.3-300 for Mw/Mn) and better processing performance.
