With the use of EPR, UV–VIS, and IR spectroscopy, calorimetry, and elemental analysis, it has been found that radicals are spontaneously formed under the action of molecular bromine on the methyl acrylate (MA) monomer at low temperatures; upon heating the system (225 K), these radicals initiate a polymerization reaction. This process is not efficient. The addition of bromine at the double bond of MA is the main reaction that occurs during the heating of the system (225 K).
