Summary: The optimum mixing and molding conditions for processing of styrene‐butadiene‐styrene (SBS) triblock copolymer filled with carbon black (CB) or polyaniline doped with dodecylbenzene sulfonic acid (Pani.DBSA) were determined. The mechanical performance of SBS/CB and SBS/Pani.DBSA composites were characterized in terms of strain and stress responses at break condition. In order to reach this goal, two mixed two‐ and three‐level factorial designs were employed. The obtained data show that the molding temperature is the most important parameter to affect the mechanical behavior of the systems. Among the systems analyzed, the SBS/Pani.DBSA blends presented the highest sensitivity to the process and molding conditions.Elongation of composites as a function of molding temperature.
