Abstract

The present invention relates to a method for monitoring a control parameter of a polymerization reaction mixture in heterogeneous phase comprising the following steps: (a) acquiring at least one NIR reflectance spectrum of said mixture; (b) calculating a value of said control parameter by means of a calibration curve which correlates the NIR reflectance spectrum with the values of said control parameter measured with a reference measurement method. The present invention also relates to an apparatus for implementing said method.
