This invention provides a process for preparing an antistatic resin composition comprising mixing and stirring a mixture of alkali metal alkylsulfonate and polyalkylene glycol to obtain a liquid mixture of the antistatic agents, which is fed into an extruder in a proper amount to homogeneously blend with a melted resin and to continuously extrude. This invention also provides an antistatic resin composition prepared thereby and a use of the composition as a master batch.
