Process for polymerizing olefins employing a catalyst prepared from organomagnesium compound; oxygen- or nitrogen- containing compound; halide source; transition metal compound and reducing agent |
摘要 |
A process for polymerizing olefins employing as a catalyst therefor, the reaction product of (A) the reaction product of (1) the reaction product of (a) an alkyl magnesium compound such as dibutylmagnesium, with (b) an oxygen-containing and/or nitrogen-containing compound such as n-propyl alcohol, or isopropylamine, with (2) a halide source such as titanium tetrachloride or silicon tetrachloride; and (B) a transition metal compound such as titanium tetrachloride and (C) a reducing agent such as triisobutylaluminum. The polymers which are produced in the presence of this catalyst and a cocatalyst such as triethylaluminum have a low catalyst support to transition metal ratio and therefore, the catalyst efficiency based on quantity of polymer per quantity of total catalyst is very high resulting in a polymer having good color and very little, if any, corrosion.
