<p>APPARATUS AND PROCESS FOR PRODUCING POLYMER5 The present invention provides an apparatus forproducing a polymer, which is able to be operated stably and continuously for a long time.In an apparatus for producing a polymer provided with a reactor, a pressure-regulating valve and a devolatilizing10 extruder so that a polymer composition obtained from the reactor is supplied to the devolatilizing extruder through the pressure-regulating valve, the pressure-regulating valve (20) comprises a valve element (1), a body (5) having a space (3) for housing the valve element (1), a stem (9)15 for supporting and controlling the valve element (1), a guide (13) for slidably guiding the stem (9), and a fluid feed port (17) through which a fluid comprising a polymerization inhibitor is fed into a gap (11) between a surface of the stem (9) and an internal surface of the20 guide (13). The gap (11) is communicated with the space (3) in the body (5) so that the fluid fed from the fluid feed port (17) flows into the space (3). Figure 1</p> |
