ResumoThe rate of polymerization of styrene in the stable free radical polymerization (SFRP) process is shown to be dependent on the excess of free nitroxide in the reaction mixture. Monomer conversion is independent of the amount of initiator and, instead, dependent on the concentration of excess nitroxide. While the excess nitroxide in styrene polymerizations is controlled by a combination of auto-initiation and termination, the actual amount of free nitroxide is proportional to the amount of initiator-adduct used.
