The kinetics of multi-site phase-transfer catalyzed free radical polymerization of methyl methacrylate (MMA) using potassium peroxy disulphate (PDS) as water soluble initiator and newly synthesized1,4- dihexadecylpyrazine-1,4-diium dibromide as multi-site phase-transfer catalyst (MPTC) has been investigated in ethyl acetate / water two phase system at constant temperature 50 ± 1°C under nitrogen atmosphere and ultrasound irradiation conditions. The rate of polymerization increases with an increase in concentrations of MMA, PDS and MPTC. The order with respect to monomer, initiator and MPTC were found to be 1.0, 0.5 and 0.5 respectively. Based on the observed results a suitable mechanism has been proposed to account for the experimental observations and its significance was discussed.
