    A process for preparing in one step a fiber-filled thermoplastic resin composition which has high fluidity and can give processed articles having high impact strength. The process comprises using equipment constituted of an extruder and a resin impregnation tank located at the outlets of the extruder, feeding a mixture of a resin component comprising polyolefin with an unsaturated carboxylic acid and an organic peroxide, that of the resin component with an unsaturated carboxylic anhydride and an organic peroxide or that of the resin component with an unsaturated carboxylic acid, an unsaturated carboxylic anhydride and an organic peroxide at a constant rate into the extruder through a first feed port located on the upstream side of the extruder, feeding at least one member selected from the group consisting of simple substances, hydroxides and oxides of alkaline earth metals at a constant rate thereinto through a second feed port located on the downstream side of the extruder wherein the above mixture has been sufficiently melt-kneaded, discharging the melt-kneaded resin mixture thus obtained into the impregnating tank, passing a roving through the resin mixture put in the tank to impregnate the roving with the mixture, and drawing the roving impregnated with the mixture out of the tank through a withdrawal port to obtain a long fiber-filled thermoplastic resin composition.
