Abstract: Noninvasive process for inline and/or online determination of polymer deposited from (meth)acrylic acid and/or (meth)acrylic esters by means of sound velocity measurements, measurements of the absorption coefficients in the infrared, near infrared, ultraviolet and/or visible region of the spectrum of electromagnetic radiation, or Raman spectroscopy, which allows precise control of the process parameters to be carried out during the thermal purification.
