Bulk functionalization of ethylene‐propylene copolymers. IV. A theoretical approach

摘要

AbstractA 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 Ioand the reaction temperature,T, shows satisfactory agreement at low values of IoandT. At higher values the molecular mechanism becomes more complex and the model is unable to fit the d
