Other transfers of coordination polymerizations

Almost nothing is known as yet about these transfers. Rabovskaya et al. considered the possibility of transfer to monomer in butadiene polymerization on 7r-alkenyl NiCl-acceptor complexes [77], 

The molecular mass of the generated macromolecules is most easily predicted for living polymerizations with rapid initiation (see Chap. 5, Sect. 8.1). Somewhat more complicated is the case of systems that, although are not living, at least polymerize without transfer. The number average polymerization degree, P, of the product is a simple function of the mean kinetic chain length, v 

The product p[M] is equivalent to the number of monomer molecules added to the active centre per unit time (s) and n is the mean life time of the centres. In radical polymerization, which are the most frequent representatives of the systems discussed, the relation 

The situation is considerably complicated by transfer in the polymerizing medium. The mean degree of polymerization is reduced 

When termination occurs by a bimolecular reaction, relation (67) is further
