D. Djurado et al., STRUCTURE AND MICROSTRUCTURE OF MIXED IONIC ELECTRONIC CONDUCTING ALTERNATE COPOLYMERS, Synthetic metals, 84(1-3), 1997, pp. 989-990
Copolymers, in which pyromellitimide units are alternating with poly(e
thylene oxide) (PEG) fragments of various lengths, have been investiga
ted in their neutral state, at room temperature, by using wide angle X
-ray diffraction (WAXRD), small angle Xray scattering (SAXS) and small
angle neutron scattering (SANS) techniques. Our results show that, de
pending on the length of included PEO fragment, the chains stacking is
driven by either of subunits of the monomer.
