Abstract

PURPOSE:To mold an undried polymer directly, by dewatering polymer particles withdrawn from a polymerization tank, supplying the polymer particles into a unidirectionally rotating twin screw extruder and dewatering, kneading and extruding the polymer particles. CONSTITUTION:A slurry containing substantially spherical polymer beads after removing most of the water by a filter or the like is fed through a metering pump 22 to a unidirectionally rotating twin screw extruder 21; introduced through a feed section 23 to blocks 23 and 24; passed through a slit means 20 having a number of narrow slits to squeeze out the water in the slurry; fed to a block 25 heated by a heater 28; pressurized by means of a screw and softened and molten. This molten polymer is introduced to a barrel 29, wherein the pressure is released, and after separating the vapors from 1st and 2nd vent ports, the molten polymer is mixed with additives from a supply inlet 32 and is discharged in the form of strand 34 from a nozzle 33. This strand is cooled in a cooling water tank 35 and cut into pellets in a pelletizer 36.
