METHOD AND DEVICE FOR MONITORING THE PROGRESS OF THE REACTION OF A POLYMERIZATION REACTION BY MEANS OF MICROWAVE OR SUBMILLIMETER WAVE RADIATION

摘要

The present invention concerns a procedure for determining the reaction progress of a polymerisation reaction by means of microwave or sub-millimeter radiation. The inventive procedure shall include the following steps:Provision of a surface (6) to absorb a reaction mixture (2) for a polymerisation reactionProvision of a transmitting unit (1) and a receiving unit (1) for microwave or sub-millimeter wave radiation, the area (6) being positioned in relation to the radiation course between the transmitting unit (1) and the receiving unit (1), where the distance between the transmitting unit (1) and the receiving unit (1) is determined and the transmitting unit (1) and the receiving unit (1) are connected to an evaluation unit,-Applying a reaction mixture (2) to the surface,Repeated irradiation of the reaction mixture (2) with FMCWmodulated microwave or sub-millimeter wave radiation by the transmitter unit (1),-Receiving microwave or sub-millimeter wave radiation after passing through the reaction mixture (2) via the receiving unit (1),Determination of the duration and/or signal weakening of the microwave or sub-millimeter wave radiation from the transmitting unit (1) to the receiving unit (1) in the evaluation unit to monitor the progress of the reaction of the polymerisation reaction.;The invention also concerns a device for carrying out the procedure
