摘要： In a process for the preparation of a supported catalyst for the preparation of polyolefins which have a component A and a component B, wherein component A consists essentially of a reaction product ofa compound of a first metal of sub groups IV to VI of the Periodic Table of the Elements with an organic compound of a second metal of main groups I to III of the Periodic Table of the Elements, said reaction being carried out at a temperature of from -60.degree. C. to +40.degree. C., andan inorganic carrier,component B being an organo metallic compound,the improvement comprising suspending the carrier in an agent which is oxygen, sulfur, and moisture free, simultaneously and separately adding to the carrier and the agent the compounds of the first and second metals in liquid or dissolved form, excluding oxygen and moisture from the reaction, and maintaining a molar ratio of the compound of the first metal to the compound of the second metal of 1:3 to 3:1.The use of the catalyst in the polymerization of ethylene both with and without the presence of .alpha. olefins is also disclosed.

摘要： An improvement in a process for the preparation of an ethylene homopolymer or a copolymer of ethylene with an .alpha.-olefin containing 3 to 15 carbon atoms by contacting the monomer or mixture of monomers in solution, suspension or in gas phase at 20.degree. to 250.degree. C. at a pressure of 1 to 50 bar with a mixed catalyst comprising a chlorine containing titanium (III) compound and an organoaluminum compound in the presence of hydrogen, the improvement residing in employing as the organoaluminum compound a trialkylaluminum compound in an amount of 0.1 to 20 mol per mol titanium (III) compound and including in the polymerization mixture oxygen at a concentration of 0.001 to 0.1 volume percent based upon the amount of ethylene. By carrying out the polymerization by including oxygen in the polymerization reaction mixture and employing trialkylaluminum compound as the organoaluminum compound the mean molecular weight of the polymer can be regulated while obtaining a desired molecular weight distribution.
