摘要：
The present invention relates to a method for oligomerization or polymerization of ethylene and/or alpha-olefins utilizing reactor equipment and other equipment wherein starting material comprising monomer(s), catalyst, cocatalyst and solvent is transferred to the reactor equipment via first piping, and product material comprising oligomer and/or polymer, non-reacted monomer(s), catalyst, cocatalyst and solvent is discharged from the reactor equipment via second piping, characterized in that the first piping, second piping, reactor equipment and/or other equipment are flushed with a product fraction obtained by said or a respective previous method prior to and/or after that oligomerization or polymerization method.
