β¦ Synopsis
Equations permitting derivation of initiation and propagation rate constants in non-ideal living polymerizations are presented. Earlier formulations are compared, simplified and tested against experimental data for the polymerizations of n-vinyl carbazole and n-butyl cyanoacrylate. Novel cases having more complex initiation processes (in the polymerization of cyanoacrylates by amines) are formulated and tested.

This review covers fundamental kinetic features of living radical polymerization (LRP). Theories on polymerization rate R p and polydispersity index (PDI) and experimental investigations into individual LRP systems are summarized. The presence of bimolecular termination, which is unavoidable in LRP
## Abstract This work studies the kinetics of living radical polymerization by means of both the nonsteady state approach and the quasiβstationary state method. Expressions for the numberand weightβaverage degress of polymerization and the polydispersity index were derived. Numerical results show t
&&Living'' free-radical polymerization (LFRP) of styrene is usually performed following two di!erent reaction procedures: by TEMPO-mediated LFRP or by atom transfer radical polymerization. The main di!erence between the previous two processes is related to how the exchange between the active and the
