  • Conductor polymers usable in the construction of completely dry batteries
    Patent number: 4943499
    Abstract: Conductor polymers prepared by anodic oxidation of compounds of general formula (I) ##STR1## in which E=O, S, Se;R.sub.1 =H or a saturated or unsaturated alkyl radical with double bonds in the vinyl or allyl position with respect to the nitrogen;R.sub.2, R.sub.3 =H or methyl radicals.These polymers have a cross-linked structure with intermonomer bonds in which possible in nitrogen-bonded vinyl groups and the aromatic rings are involved, and delocalized positive charges in the chain neutralized by counter-ions such as Cl.sup.-, BF.sup.-.sub.4, ClO.sup.-.sub.4 or PF.sup.-.sub.6. These polymers can be used in the construction of rechargeable batteries of completely solid state.
