Abstract For various applications it is necessary to lower the specific surface resistivity of polymers in an electrostatically conductive area. To improve the antistatic properties of sheet molding composites (SMC) usually conductive inorganic additives, like carbon black, inorganic salts, metal powder, or CNTs, are mixed physically into the matrix. A newly developed concept for antistatic treatment is using oligomeric/polymeric additives, which are synthesized on the base of ingredients of the used polymeric matrix itself. The received additives are compatible with the matrix. Furthermore, the migration of the additives to the surface is prevented and in the case they exhibit double bonds they are able to be linked in the polymeric network permanently by covalent bonds. So unsaturated, polymer-based antistatic additives with ionic units were developed for unsaturated polyester resin based SMC. The synthesis was realized by polymer analogous reactions and polycondensation reactions from monomer building blocks with ionic units. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
