Abstract

PURPOSE: To improve productivity, by coagulating a latex of a polymer plasticizable at 100W300°C, dehydrating and drying the coagulated polymer by passing the polymer together with vinyl polymer pellets through a screw type squeezing dehydration dryer and continuously recovering the polymer in the molten state.
CONSTITUTION: Into a coagulation tank 3 is introduced from a storage tank 1 a latex of a polymer which is hard at normal temperature and is plasticizable at 100W 300°C, such as a vinyl polymer latex, a latex of a graft polymer prepared by grafting a vinyl monomer onto a rubbery polymer or a latex of these mixed polymers. A coagulant is introduced to the tank 3 from a storage tank 2. The coagulation is continuously fed to a filter 4. Then, the polymer cake is conveyed at a constant rate to a screw dehydrator 8. On the other hand, vinyl polymer pellets are fed from a hopper 5 through a metering feeder 6 to the dehydrator 8. The polymer dried in the dehydrator 8 is passed through a cooling bath 9 and cut and pelletized by a cutter 10. The volatile matters from the dehydrator 8 are sucked and exhausted via a vent receiving tank 11 by a vacuum pump 5.
