Abstract: Catalysts for the polymerization of C2-C20-olefins are preactivated by a process in which the catalyst is first mixed with the respective monomer, then, if appropriate, the respective cocatalyst is added and the resulting mixture is subsequently subjected to preactivation in a tube reactor and the catalyst which has been preactivated in this way is finally introduced into the actual polymerization reactor, wherein the mixture of catalyst, any cocatalyst and monomer is passed through the tube reactor in turbulent plug flow at a Reynolds number of at least 2 300.

Abstract: The invention relates to a method for preactivating catalysts for polymerisi ng C2-C20 olefins. According to said method, the catalyst is first mixed with t he respective monomer. The co-catalyst is then added, optionally, and the resulting mixture is subjected to preactivation in a tubular reactor. Finall y, the catalyst that has been preactivated in this way is introduced into the actual polymerisation reactor. The mixture of the catalyst, optionally, the co- catalyst and the monomer is guided through the tubular reactor in the form o f a turbulent plug flow with a Reynolds number of at least 2300.
