Abstract
A composition comprises a) from about 80 to 99.5 percent by weight of a functionalized film-forming polymer matrix; b) from about 0.5 to 20 percent by weight of an intrinsically conductive polymer dispersed in the matrix; wherein the functionalized film-forming matrix controls the electrical conductivity in the composition, within a range of less than 5 orders of magnitude from about 10.sup.5 to about 10.sup.10 ohm/square, and is selected from the group consisting of acyclic organic hydroxyl compounds, and acrylates and methacrylates, containing at least one functionality selected from the group consisting of urethanes, epoxies, glycols, hydroxyls, polyesters, ethoxylates and propoxylates. The present invention also provides processes for making a conductive coating or blend compositions.
