Abstract
PURPOSE: To prepare a chloroprene copolymer useful as an oil-resistant rubber, without emitting irritative odor under improved working conditions on the standpoint of environmental sanitation, by drying the copolymer of chloroprene and an unsaturated nitrile etc. with an expansion-type dryer.
CONSTITUTION: The water-containing coagulum 8 of a copolymer of chloroprene and an unsaturated nitrile (e.g. acrylonitrile) or monomers copolymerizable therewith (e.g. styrene) is continuously fed from the inlet 1 of an expansion-type dryer. The coagulum is transferred to the compression zone 2 by rotating the screw 5. A considerable amount of water 9 is squeezed out by compression action and discharged from the outlet 3 through the screen 7. The coagulum is transferred forward and injected through the narrow nozzle of the die 4 under high temperature and high pressure caused by the frictional heat to change the residual water to steam 10 in a moment, and consequently to give the dried polymer 11.
