Method for monitoring a control parameter of a polymerization reaction and relative apparatus for implementing said method

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. 本发明涉及监测非均相聚合反应混合物控制参数的方法，包括以下步骤：(a)获得所述混合物的至少个NIR反射光谱；(b)通过NIR反射光谱与参比测量法测定的所述控制参数值相关联的校正曲线来计算所述控制参数的值。本发明还涉及实施所述方法的装置。
