Abstract

PURPOSE: To recover the solvent in good yields, by separating and drying the polymer by feeding a reaction solution containing a chlorosulfonated PE polymer into an extruder equipped with a vent port.
CONSTITUTION: A chlorosulfonated PE polymer obtained by dissolving a PE polymer in CCl4 and chlorosulfonating the polymer with Cl, SO2 and/or sulfuryl chloride is fed through a reaction kettle 1 and a preheater 4 to the upper part of a preconcentrating equipment 6 connected to a vacuum generation means 5, and concentrated therein to a polymer concentration ≥40wt% and at the same time, allowed to fall in the form of strand. The strand-form polymer is fed to an extruder 10 equipped with a vent port by means of a screw-type discharger 9. An antioxidant is fed from a storage tank 17 and at the same time CCl4 is v ented from a vent port 17. The polymer is dried, cut with a cutter and conveyed to a packaging equipment 20.
