Effect of sonication on nitroxide-controlled free radical polymerization of styrene.
Effect of sonication on the autopolymerization of styrene in the presence of 2,2,6,6-tetramethylpiperidinyl-1-oxy as the mediating radical was investigated at 110-135 degrees C. The thermal polymerization under sonication proceeded in the manner of a "living" radical polymerization to afford well-defined polystyrene. The sonication was found to decrease the induction period and increase the polymerization rate.
