Process for polymerizing cf=cfci in slurry system

Claim 1

A PROCESS FOR POLYMERIZING TRIFLUOROCHLOROETHYLENE TO PRODUCE A SOLID POLYMER WHICH COMPRISES INTRODUCING TRIFLUOROCHLOROETHYLENE INTO ONE END OF A HORIZONTAL ELON GATED REACTION ZONE MAINTAINED AT A TEMPERATURE OF ABOUT 32* F. AND A PRESSURE OF ABOUT 30 POUNDS PER SQUARE INCH GAGE, POLYMERIZING MONOMER IN SAID REACTION ZONE TO SOLID POLYMER TO FORM A SLURRY CONTAINING NOT MORE THAN 12 PER CENT SOLID POLYMER, FLOWING SAID POLYMER SLURRY HORIZONTALLY THROUGH SAID REACTION ZONE, REMOVING MONOMER VAPORS FROM SAID REACTION ZONE, COOLING AND CONDENSING SAID MONOMER VAPOR THUS REMOVED AND RETURNING CONDENSATE TO SAID REACTION ZONE TO CONTROL THE TEMPERATURE THEREOF, REMOVING MONOMER-POLMER SLURRY FROM THE OTHER END OF SAID REACTION ZONE, PASSING A SLURRY CONTAINING MONOMER AND SOLID POLYMER FROM SAID REACTION ZONE TO A SPRAY DRYING ZONE, SPRAY DRYING THE MONOMER SLURRY AT A TEMPERATURE AT LEAST ABOUT 150* F. TO FORM FINELY DIVIDED SOLID POLYMER IN MONOMER VAPOR, SEPARATING SOLID POLYMER FROM MONOMER VAPOR AND RECOVERING SOLID POLYMER AS A PRODUCT OF THE PROCESS, RETURNING A PORTION OF THE AFORESAID MONOMER VAPOR TO SAID DRYING ZONE AT AN ELEVATED TEMPERATURE TO AID IN THE DRYING OF SAID SLURRY, PASSING ANOTHER PORTION OF THE AFORESAID VAPOROUS MONOMER CONTAINING ENTRAINED SOLID POLYMER TO A CONCENTRATION ZONE, IN SAID CONCENTRATION ZONE CONTACTING VAPOROUS MONOMER CONTAINING ENTRAINED SOLID POLYMER WITH LIQUID MONOMER, AND RECOVERING A LIQUID CON DENSATE CONTAINING SOLID POLYMER AND RECYCLING SAME TO SAID HORIZONTAL REACTION ZONE.
