| titleOfInvention | Process for the manufacture of homo- and copolymers of ethylene by Phillips catalysts |
| abstract | The framework is ethene polymerization by Phillips catalysis using (1) a supported catalyst which is loaded with chromium, phosphorus and aluminum, and (2) a cocatalyst, (1) having been obtained by (1.1) a with chromium, phosphorus as well as aluminum-loaded catalyst pre-product from a silicate carrier, a selected chromium compound, a selected phosphorus compound and a selected aluminum compound, and then (1.2) the catalyst pre-product is heated in an oxygen-containing gas stream. It is characteristic that one uses (1) one that has been obtained by - first in each case in the type and manner - (1.1) first (1.1.1) from (1.1.1.1) a finely divided one produces a suspension of silicate and (1.1.1.2) an inert organic solvent, (1.1.2) then (1.1.2.1) in an inert organic solvent (1.1.2.2) combines an organic chromium compound with (1.1.2.3) an aluminum trialkyl, (1.1.3) then (1.1.3.1) combines the suspension resulting from (1.1.1) with (1.1.3.2) a phosphoric acid or phosphoric acid ester and (1.1.3.3) the product obtained from (1.1.2), ( 1.1.4) finally evaporate the suspension obtained in (1.1.3) to dryness, and then (1.2) secondly (1.2.1) first treats the preliminary product obtained from (1.1) with a stream of nitrogen, then (1.2.2) the intermediate product obtained from (1.2.1) is heated in an oxygen-containing gas stream, and finally (1.2. 3) the intermediate product obtained from (1.2.2) is treated with a stream of nitrogen; and as (2) both a lithium alkyl and a boron alkyl. |
