Abstract
Olefins are polymerized in the presence of (I) solid supported catalysts which are prepared by (A) reacting in the presence of a diluent such as n-hexane a mixture of (1) the reaction product of (a) an organomagnesium compound such as dibutyl magnesium and (b) a diol such as 1,8-octanediol and (2) a transition metal halide such as titanium tetrachloride and (B) recovering the solid precipitate such as by decanting and (C) washing the solid with a solvent such as n-hexane and (II) a suitable activating agent. The resultant polymers have a relatively broad molecular weight distribution.
