A theroretical model is developed for the bulk functionalization of ethylene–propylene co‐polymers on the basis of the molecular mechanism proposed in previous papers, with certain simplifying assumptions: (1) A steady state regime for all the radical species is hypothesized; (2) a number of termination reaction are neglected; (3) no monomer homopolymerization is allowed to occur. An analytical expression is derived in such a way. A comparison of the theoretical predictions with some experimental data, obtained varying the radical initiator concentration [I] o and the reaction temperature, T , shows satisfactory agreement at low values of [I] o and T . At higher values the molecular mechanism becomes more complex and the model is unable to fit the data.
