Abstract
A method for producing a reinforced thermoplastic resin composition in a stable manner for long periods of time, comprising providing a melt-kneading apparatus with a plurality of supply ports arranged in line with the direction, along which a molten resin flows, supplying a polyolefin resin, a solid modifier and a solid radical generator through a first supply port positioned on the most upstream side of the extruder; supplying a flake inorganic filler through a second supply port arranged at a position on the downstream side of the first supply port; supplying a fibrous reinforcing material through a third supply port arranged at a position on the downstream side of the second supply port; and supplying an unsaturated silane compound through a liquid-introducing port arranged at a position on the immediately downstream side of the first supply port and on the upstream side of the second supply port, to thus melt and knead these components. Also provided is a production apparatus for practicing the production method.
