Abstract: The invention relates to the use of aldoximes, ketoximes which are not derived from quinones, hydroxime acid esters, and N-acyl-hydroxylamine derivatives for stabilising ethylenically unsaturated compounds containing oxygen and/or nitrogen, such as (meth)acrylic acid (esters). Co-stabilisers, such as transition metal salts, phenols, quinones, or hydroquinones, N-oxyls, aromatic amines or phenylenediamines, urea derivatives, compounds containing phosphorus, compounds containing sulphur, and sulfonamides, can be used with the above-mentioned substances. Preferably, a gas containing oxygen, such as air, is present.

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.
