In the Ziegler - Natta polymerization takes also place the transfer reactions of the chain activity as demonstrated by the fact that the molecular weight reaches a relatively constant value in a short time after the initiation of reaction. These reactions include ... [Pg.308]

Polymerization of vinylferrocene, for example, is carried out by different initiations including the Ziegler-Natta type one [3,201]. The transition metal ion such as Fe(II) can participate during the radicalic polymerization by transfer of an electron from a Fe atom to the terminal chain radical. Therefore higher values of constant of chain transfer are determined A ct/A p = 8 x 10 at 60 °C for styrene kctlkp = 6 x 10 . ... [Pg.694]
