The kinetics of graft copolymerization of vinyl acetate on polymethyl methacrylate was investigated. Polymethyl methacrylate was preirradiated in the presence of air by gamma rays, the polymer being used as the initiator of the polymerization in the one-phase system. The rate of reaction for low conversion is proportional to the concentration of monomer raised to the power of 3/2 and to the concentration of initiator to the 1/2 power. The reaction satisfied the kinetic equation for ordinary addition polymerization if the decrease of the amount of the initiator during the process is taken into consideration. The activation energy of this process was found. The quantity of the homopolymers produced in this reaction is negligible and need not be taken into account in rough calculations as far as kinetics are concerned. (auth)
