Apparatus for treating thermoplastic resin

摘要

Apparatus for treating a thermoplastic resin is made up of a feed barrel supplied with the thermoplastic resin, a slit barrel for discharging a liquid component of the resin, a press-in barrel into which a polymer is admitted under pressure, and a vent barrel having a vent opening for discharging vaporized substance generated by the thermoplastic resin and the polymer. These barrels are serially interconnected to from a cylinder which contains a screw for kneading a mixture of the resin and the polymer. The kneaded mixture is extruded as a strand.
