Configuration statistics of copolymers obtained by a complex-radical mechanism

Modern aspects of quantitative theory of free-radical copolymerization

“…There are a number of models describing multicomponent systems which account for. the influence of the penultimate unit [47], the formation of the binary [48] and triple [49] complexes and also for the depolymerization reactions [50]. However, up to now, all such models have a limited range of application since the current experimental techniques do not allow one to determine correctly a great number of their kinetic parameters.…”

“…In contrast to the above mentioned models, the similar statistical description of the products of the complex-radical copolymerization occurring through the scheme (2.5) has been carried out quite recently [37,49,[55][56][57][58][59][60]. Within the framework of this Seiner-Litt model, both copolymer composition [37,49,[55][56][57][58] and fractions of the different triads and blocks of the monomer units in the macromotecutes were calculated [57].…”
