Kinetics of polymerization of ethyl methacrylate initiated by 2,2'-azoisobutyronitrile (AIBN) was studied applying the "dead-end" theory. This theory is appropriate to examine the solution polymerization of this monomer in benzene at 8 > 60°C. Radical polymerizations of ethyl methacrylate were carried out at 60 -110 "C. By using the procedures of the dead-end theory, the rate of decomposition and the initiator efficiency of AIBN were determined. Kinetic parameters of the solution polymerization of ethyl methacrylate were calculated and the results were compared with the literature values.
