Solid catalysts for the polymerization of olefins and process for the production of olefin polymers therewith

Abstract

A solid catalyst for olefin polymerization, obtained by reacting a least one of a hydropolysiloxane compound, having the formula R H SiO , a silane compound of formula R Si(OH) , and condensates of the silane, with a compound of formula (MgR ) .(R MgX) to form a reaction product. The reaction product is reacted with an alcohol, having 1 to 4 carbon atoms, to obtain an intermediate product. The intermediate product, is then reacted with water to obtain reaction product. An organoaluminum oxy compound and a metallocene compound are carried on the solid reaction product. The solid catalyst may be used for olefin polymerization. The catalyst requires no deashing treatment and produces a polymer having high bulk density and narrow particle size distribution. Thus the solid catalystenables control of particle size of the polymer in a simple easy manner, and shows no adhesion of polymer onto the inner wall of autoclave.
