A local model is set up for the conductivity in alkali-doped polyacetylene Ž . PA based on results of ab initio and semiempirical calculations. At low doping levels, Ž . solitons and polarons appear naturally in the nondegenerate ground state. Alkali atoms donate their valence electrons to neutral s

## Abstract Lignosulfonic acid doped polyaniline (LIGNO‐PANI) is a water‐dispersible conducting polymer. The incorporation of dopants to achieve higher conductivities in addition to lignosulfonates during the polymerization process results in prohibitively long initiation times. A variety of transi
