摘要： Ethane polymers are prepared by Phillips catalysis using (1) a supported catalyst which is laden with chromium, phosphorus and titanium and (2) a cocatalyst, (1) being obtained by a procedure in which (1.1) a catalyst intermediate laden with chromium, phosphorus and titanium is prepared from a silicate carrier, a selected chromium compound, a selected phosphorus compound and a selected titanium compound, and (1.2) the catalyst intermediate is then heated in an oxygen-containing gas stream. In the process, the supported catalyst (1) used is one which is obtained (using specific methods and substances in each case) by a procedure in which (1.1) in a first stage (1.1.1), a suspension is first prepared from (1.1.1.1) a finely divided silicate carrier and (1.1.1.2) an inert organic solvent, (1.1.2) a suspension is then prepared from (1.1.2.1) a finely divided chromium trioxide and (1.1.2.2) an inert organic solvent, (1.1.3) thereafter (1.1.3.1) the suspension resulting from (1.1.2) is combined with (1.1.3.2) a phosphate or phosphite, (1.1.4) then (1.1.4.1) the suspension obtained from (1.1.1) is combined with (1.1.4.2) the reaction product obtained in (1.1.3), (1.1.5) thereafter (1.1.5.1) the suspension formed in (1.1.4) is combined with (1.1.5.2) a titanate, (1.1.6) finally the suspension obtained in (1.1.5) is evaporated to dryness and then (1.2) in a second stage, (1.2.1) the intermediate obtained in (1.1) is first treated with a nitrogen stream, (1.2.2) an intermediate obtained in (1.2.1) is then heated in an oxygen-containing gas stream and finally (1.2.3) the intermediate obtained in (1.2.2) is treated with a nitrogen stream, and a lithiumalkyl is used as (2).
