Method for preparing latex by emulsion (co) polymerization of ethylenically unsaturated monomers, with direct inline monitoring by raman spectroscopy

   
   

The invention concerns a novel method for preparing latex by emulsion (co)polymerization of ethylenically unsaturated monomers, wherein the direct inline monitoring is carried out by Raman spectroscopy. The invention also concerns latex compositions obtainable by the emulsion (co) ploymerization method whereof the direct inline monitoring is performed by Raman spectroscopy. The invention further concerns a device for implementing said method, said device comprising a reactor, at least an optical probe, a Raman spectrometer, optical fibers, a computer and a regulating automaton.
