Room temperature electric conductivities of soluble and insoluble
fractions of P(I-co-II) and P(II) virgin polymers were equal
to 10−9, 3×10−9 and 10−11 S/m, respectively. Electric conductivities,
Ns (spin/g), Bpp (mT) and g-factor values for undoped
examples of both soluble and insoluble fractions of polymers were
nearly the same, except for that of the insoluble fraction of P(II)
polymer: its electric conductivity was lower and Ns value was
higher as compared with results obtained for all other samples
(Figs. 3–5).
