Title:
オレフィン重合に適する触媒の調製法
Document Type and Number:
Japanese Patent JP3857723
Kind Code:
B2
Abstract:
The invention relates to a method for the preparation of a catalyst suitable for the polymerisation of an olefine by contacting a magnesium compound with a halogenized Ti compound, characterised in that the magnesium compound is obtained by: a) contacting metallic magnesium with an aromatic halide RX, where R is an aromatic group containing from 6 to 20 carbon atoms and X is a halide, whereupon the dissolved reaction product I is separated from the solid residual products and then b) adding an alkoxy group or aryloxy group-containing silane compound to the obtained reaction product I at a temperature of from -20 to 20 DEG C, whereupon the precipitate formed is purified to obtain reaction product II, which subsequently during a step c is contacted with TiCl4 as halogenized Ti compound and is purified to obtain a catalyst.
