The invention discloses a method for the production of a polymerized product comprising the following steps: - providing a polymerization device to which a polymerization mixture and a separation medium can be applied and wherein flow of said mixture and medium can be conducted in appropriate ducts for said mixture and medium, - transporting said polymerization mixture in a duct of said polymerization device thereby allowing the polymerization reaction, - transporting said mixture in a duct of said polymerization device in a continuous flow, - interrupting said continuous flow of said mixture with said separation medium so as to obtain consecutive volumes of said mixture and volumes of said separation medium, - further transporting said consecutive volumes of said mixture and volumes of said separation medium in a duct of said polymerization device wherein said mixture further polymerizes to obtain a discontinuous polymerized product, and removing said discontinuous polymerized product from said polymerization device.
