Homopolymerization of styrene (S) was performed using classical batch mode RAFT polymerization. In a 100 mL round bottom flask, 570 mmol (59 g, 200 equiv., 8 M) of monomer Styrene, 2.85 mmol (1 g, 1 equiv.) of DoPAT RAFT agent and 0.28 mmol (0.04 g, 0.1 equiv.) of AIBN were dissolved in 5 mL of toluene. Few drops of DMF were added as an internal standard for 1H NMR analysis. A sample from this initial solution was dissolved in CDCl3 and was measured as the to sample in 1H NMR spectrometer. Subsequently, the flask was purged with argon gas for 30 minutes. The solution was left to react at 65 °C in an oil bath with magnetic stirring for 50 hours. The reaction was quenched by lowering the temperature and by exposing the reaction mixture to air. A sample from the reacted solution was dissolved in CDCl3 and was measured as the tfinal sample in 1H NMR spectrometer. Monomer conversion was calculated using the integral changes at the vinyl peaks of monomer in to and tfinal 1H NMR spectra. The synthesized polymer was purified via precipitation using cold methanol. The final product was dried in vacuo over 24-48 hours.
