The kinetics of phase-transfer catalyzed radical polymerization of benzyl methacrylate (BMA) using potassium proxydisulphate (PDS) as water soluble initiator and 1,4-dihexadecylbenzopyrazine-1,4-diium bromide as multi site phase-transfer catalyst(MPTC) has been investigated in ethyl acetate / water two phase system assisted by ultrasound irradiation at constant temperature 70 + 1°C under nitrogen atmosphere. The rate of polymerization increases with an increase in concentrations of BMA, PTC and PDS. The order with respect to [BMA], [MPTC], and [PDS] were found to be 1.019, 1.098 and 0.502 respectively. Based on the observed results a suitable mechanism has been proposed to account for the experimental observations followed by a discussion on its significance.
