Abstract
A production process for a long fiber-filled thermoplastic resin composition using an apparatus having an extruder with at least two raw material feeding ports and a resin impregnating bath at the tip of the extruder, comprising the steps of feeding a resin mixture to a first feeding port provided at an upstream position of the extruder, feeding alkaline earth metals to a second feeding port provided at a downstream position of the extruder, melt-kneading to a mixture, allowing the obtained molten resin mixture to flow into the resin impregnating bath, passing a continuous fiber bundle through the molten resin mixture in the resin impregnating bath to impregnate the continuous fiber bundle with the resin mixture.
