PURPOSE:To provide an antistatic agent composed of a specific comb-type graft polymer containing hydrophilic component and anker component, having excellent compatibility with synthetic polymers, and exhibiting excellent antistatic effect continuously without lowering the characteristics of the polymer. CONSTITUTION:The objective antistatic agent is composed of a comb-type graft polymer containing an SO3M group and/or polyethylene oxide component and a component compatible with polymeric materials. The graft polymer is preferably the one synthesized by the macromonomer process and containing 5-90wt%, preferably 10-80wt% of the hydrophilic component. The M of the SO3M of the hydrophilic component is alkali metal, preferably K, Na or Li. The amount of the antistatic agent to be added to the synthetic polymer is 0.5-10wt%, preferably 1-5wt%.
