Abstract

PURPOSE: To obtain a bead polystyrene having a uniform particle size, by prepolymerizing styrene by bulk polymerization, dispersing the prepolymerizate in a catalyst dispersion and suspension-polymerizing the resulting dispersion.
CONSTITUTION: A styrene monomer is fed into a bulk polymerization tank 1 and prepolymerized therein by bulk polymerization. This propolymerizate is fed into a mixer 4 through a pipe 3 fitted with a valve 2. A continuous phase is fed by a pump 7 into the mixer 4 through a pipe 8 from a water tank 7 containing a heater 5. The mixer 4 functions so as to disperse the prepolymerizate fed from the bulk polymerization tank 1 in the continuous phase. The formed suspension is transferred to a suspension polymerization tank 9. In the suspension polymerization tank 9, the prepolymerizate contained in the suspension fed from mixer 4 is suspension-polymerized under agitation by an impeller 10.
