The present invention relates to a process for quantitative monitoring of the composition of an oligomer/monomer mixture containing a plurality of mixture components. The process according to the invention is characterized in that the quantitative composition of the oligomer/monomer mixture is measured by means of an NIR spectroscopy measuring unit (7) under the application of a chemometric method, wherein the liquid pressure in the quantitatively monitored oligomer/monomer mixture pL>3 bar. Further, the invention relates to an apparatus for quantitative monitoring of the composition of an oligomer/monomer mixture containing a plurality of mixture components, and an installation (100) for producing a polymer product.
A method for quantitative monitoring of a composition of an oligomer/monomer mixture containing a plurality of mixture components, wherein a quantitative composition of the oligomer/monomer mixture is measured by means of a Near-infrared (NIR) spectroscopy measurement unit using a chemometric method, wherein a liquid pressure in the quantitatively monitored oligomer/monomer mixture is pL>3 bar.
