The present invention relates to a process for preparing a catalyst solid
for olefin polymerization which is obtainable by bringing A) at least one
organic transition metal compound, B) at least one organometallic
compound, C) at least one organic compound having at least one functional
group containing active hydrogen, D) at least one Lewis base and E) at
least one support, into contact with one another, wherein the components
are combined in any order without any work-up of the mixtures present at
intermediate stages being carried out. In addition, the invention relates
to the use of the catalyst solid for olefin polymerization, to catalyst
solids obtainable by this process, to catalyst systems in which these
catalyst solids are present and to a process for the polymerization of
olefins in which these catalyst solids are used.
