摘要： Disclosed is a non-invasive method for the inline and/or online determination of polymer separated from (meth)acrylic acid and/or (meth)acrylic acid esters by means of sound velocity measurements, measurements of the absorption coefficients in the infrared range, near infrared range, ultraviolet range, and/or visible range of the electromagnetic radiation spectrum, and Raman spectroscopy. Said method allows the operating parameters to be controlled in a specific manner during thermal purification.
