A special light saber blade coating and a process to make the coated blade which provides a replica sword as an authentic-looking device as seen in “Star Wars” movies, out-takes and re-enactments. The sword blade device provides a unique and realistic replica of the light saber. The process using epoxy, color glitter and other materials is a set of repetitive steps to place the mixture of epoxy onto the blade with a method that is economic and repeatable producing a light saber blade with quality and durability.

When measuring the molecular mass distribution of conductive aniline polymer of formula (1) by GPC and converting its retention time into molecular mass (M) in terms of sodium polystyrene sulfonate, for the molecular mass (M), the area ratio (X/Y) of the area (X) of a region of 15,000 Da or more to the area (Y) of a region of less than 15,000 Da is 1.20 or more. A method for producing such a polymer includes: polymerization step (Z1) where specific aniline derivative (A) is polymerized in a solution containing basic compound (B), solvent (C), and oxidizing agent (D) at a liquid temperature lower than 25° C.; or polymerization step (Z2) where specific aniline derivative (A) and oxidizing agent (D) are added to and polymerized in a solution of a conductive aniline polymer (P-1) with a unit of formula (1) dissolved or dispersed in a solvent (C). ##STR00001##
