摘要： The present invention relates to a novel catalyst component for ethylene polymerization comprising vanadium and titanium. Moreover, when the vanadium/titanium containing catalyst of the present invention is employed with an aluminum-containing cocatalyst enhanced activity as well as melt index is obtained.The present invention is directed to a novel halosilane cocatalyst component which, when used in conjunction with an aluminum containing cocatalyst, is effective in increasing the activity of a silica supported titanium/vanadium containing solid catalyst component in the polymerization of ethylene and/or .alpha.-olefins. In addition to the increased catalytic activity, the polymers produced by the present invention exhibit improved melt index values compared with melt index values typically obtained using prior art catalyst systems.

摘要： A novel catalyst support and a method for preparation thereof, characterized by the presence of selected amounts of a hydrocarbon soluble magnesium-containing compound applied to the support relative to solvent, wherein a surface uniformly and essentially continuously moistened with the solvated magnesium compound in a condition of incipient precipitation to permit the formation of a regular essentially continuous distribution of the magnesium compound onto and conforming to the support material. The drying process under these conditions is effective in maintaining to a high degree the effective surface area and pore volume of the material. The support containing the adsorbed magnesium is then dried in a controlled manner to essential incipient wetness conditions providing a regular spatial distribution of stacked reticular magnesium values at a level of one to five molecular monolayers on the support.A representative process for polymerizing or copolymerizing olefins providing stereospecific polymers such as propylene is disclosed.
