Method of polymerizing styrene
Abstract
Abstract PROCESS FOR TREATING VISCOUS FLUIDS, SUCH AS ARE OBTAINED DURING THE POLYMERIZATION OF MONOMERS, E.G., STYRENE, COMPRISING, CONTINUOUSLY FEEDING THE FLUID TO AND AGITATING THE FLUID IN A MIXING AND REACTIN ZONE WHEREIN IT IS CAUSED TO FLOW IN REVERSE DIRECTIONS AT HIGH FLOW RATES AND INTO CONTACT WITH HEAT EXCHANGE SURFACES WHEREBY THE POLYMERIZING MIXTURE IS SIMULTANEOUSLY AND PERFECTLY MIXED WHILE A LARGE AMOUNT OF SENSIBLE HEAT IS ABSORBED, SUBJECTING THE FLUID TO ONE OR MORE STAGES WHEREINE IT IS CONTINUOUSLY MOVED THROUGH A TUBLULAR HEAT EXCHANGE ZONE, THEN THROUGH AN ANNULAR HEAT EXCHANGE ZONE CONTAINING, IN ADDITION, HEAT EXCHANGE TUBES, ACCOMPAINED BY RECIRCULATING AT HIGH FLOW RATES OF THE FLUID FROM ONE ZONE TO THE OTHER WHILE CONTACTING IT WITH HEAT EXCHANGE SURFACES AND WHILE MAINTAINING AS SMALL A TEMPERATURE DIFFERENTIAL BETWEEN THE HEAT EXCHANGE SURFACES AND THE FLUID AS PROVIDES THE DESIRED HEAT EXCHANGE.
