    摘要: In a method of making impact-resistant modified thermoplastic materials, thermoplastic material is introduced in a continuously operating twin-screw extruder having two screws rotating in a same direction and plasticized. Admixed to the thermoplastic material in the extruder at a location well downstream of the feed area of the thermoplastic material is an additive, e.g. impact-resistant modification agent, reinforcing agent, or alloying agent, to produce an extrudate which is conveyed for injection into an injection mold alternately via two injection cylinders or via a storage cylinder and one injection cylinder.
