The invention relates to a method for monitoring the extent of a solution polymerization reaction by means of a fluorescent probe sensitive to variations in viscosity dissolved viscosity in the reaction mixture, in which process the probe has an AIE (aggregation-induced emission) behaviour and the viscosity trend in the system is quantified by means of one or more photodiode photodetectors, which convert(s) the fluorescence signal into a variation of the electric potential and transmits it for reading and recording without resorting to spectrofluorometers.The method is particularly suitable for monitoring the synthesis of polyurethanes.
