A typical procedure for synthesis of peroxide containing co-and terpolymers was as follows . Copolymerization was performed in acetone at a temperature of 60 °C under argon (nitrogen) blanket at a total monomer concentration of 4 mol/L using benzoyl peroxide (BP) or lauryl peroxide (LP) as an initiator at concentration of 32 mmol/L. For the process control, the monomer conversion was determined by gas chromatography from aliquots of the reaction mixture taken every 2 hours. When reaching the total monomer conversion of 85-90%, the process was stopped by cooling the reactive mixture down to room temperature, and the product was precipitated by dropwise addition of the reactive mixture into a mixture of hexane and petroleum ether (1/1; w/w). The products were further purified by double precipitation from acetone solution into a mixture of hexane and petroleum ether (1/1; w/w). Polymer composition was evaluated using elemental analysis, reverse potentiometric titration, and gas chromatography.
