Abstract
Cationic, electrically conductive polymers are mixed with multifunctional anionic compounds and/or anionic polymers to form a polysalt complex which exhibits markedly improved properties. Specifically, solvent holdout to parafinic solvents and to toluene are considerably improved, and the tackiness of the resulting film is notably decreased. The polysalt products also exhibit very good filmability on plastic substrates whereas the cationic polymer alone normally forms very poor films on such substrates.
