Abstract

A PROCESS FOR PREPARING A STYRENE POLYMER BY CONTINUOUSLY POLYMERIZING A STYRENE MONOMER IN THE PRESENCE OF A SOLVENT FOR THE STYRENE POLYMER IN A POLYMERIZATION REACTOR EQUIPPED WITH A STIRRING BLADE IN WHICH AN UP-AND-DOWN CIRCULATING FLOW GENERATION TYPE STIRRING BLADE IS USED AS THE STIRRING BLADE; THE TEMPERATURE OF THE SOLUTION IN THE POLYMERIZATION REACTOR IS IN THE RANGE OF 100 TO 150°C; THE VISCOSITY OF THE SOLUTION IN THE POLYMERIZATION REACTOR IS IN THE RANGE OF 0.5 TO 50 POISE; AND THE GAS LINEAR VELOCITY OF THE EVAPORATED VAPOR OF THE SOLVENT AND THE MONOMER IN THE POLYMERIZATION REACTOR IS IN THE RANGE OF 0.00 1 TO 0.14 M/SEC. ACCORDING TO THE PRESENT INVENTION, THE EVAPORATION LATENT HEAT OF THE MONOMER AND THE SOLVENT CAN BE UTILIZED TO REMOVE POLYMERIZATION HEAT AND STIRRING HEAT AT THE TIME OF THE PREPARATION OF THE STYRENE POLYMER, AND THE APPARENT VOLUME EXPANSION OF THE POLYMERIZATION SOLUTION CAN BE MINIMIZED.FIGURE 6
