Abstract
In a solution polymerization process the increase in gel content in the solution at one or more locations may be detected by monitoring the structure of a spectrum obtained by analyzing the reaction at said one or more locations using a spectrometer selected from the group consisting of infrared spectrometers, near infrared spectrometers and Raman spectrometers.
