PROBLEM TO BE SOLVED: To provide method and apparatus of rubbery polymer which can enhance operability (simplifying operation and reducing the loss of a product even when the kind of a rubbery polymer to be produced is changed over and shortening a changeover time), reduce a process and machinery and achieve the reduction of equipment cost and production cost in the production of a rubbery polymer. SOLUTION: A coagulation soln. is added to a cementitious rubber soln. after polymerization to precipitate a rubbery polymer component which is, in turn, dried to obtain a rubbery polymer in a dry state. In this method, the cementitious rubber soln. and the coagulation soln. are respectively separatelysupplied to the area immediately before the inlet of a rotary blade 36 of a pump 14 equipped with grinding function and brought to a contact state to immediately sent to a dryer 16 by the pump 14. |
