Abstract 1. IN THE FREE-RADICAL POLYMERIZATION PROCESS FOR THE PRODUCTION OF POLYMERIZATES IN AN AQUEOUS DISPERSION CONTAINING AT LEAST 60% OF POLYVINYL CHLORIDE, WITH LOW POLYMER DEPOSITS, WHICH COMPRISES THE STEPS OF OIXING (1) MONOMERS SELECTED FROM THE GROUP CONSISTING OF VINYL CHLORIDE AND MIXTURES OF VINYL CHLORIDE WITH UP TO 40% BY WEIGHT OF OLEFINICALLY MONO-UNSATURATED COMPOUNDS COPOLYMERIZABLE WITH VINYL CHLORIDE, (2) A FREE-RADICALFORMING POLYMERIZATION CATALYST, (3) DISPERSION STABILIZERS SELECTED FROM THE GROUP CONSISTING OF PROTECTIVE COLLOIDS, EMULSIFIERS AND MIXTURES THEREOF, AND (49 WATER, HEATING SAID MIXTURE UNDER AGITATION TO A POLYMERIZATION TEMPERATURE OF BETWEEN 0* C. AND 80* C. AND RECOVERING SAID POLYMERIZATE, THE IMPROVEMENT WHICH CONSISTS IN CONDUCTING SAID POLYMERIZATION IN A CONFINED SPACE AND SPRAYING A FINE SPRAY OF WATER IN A TOTAL AMOUNT OF FROM 20% TO 100% BY VOLUME OF THE VOLUME OF SAID MONOMERS, ONTO THE EXPOSED SURFACE OF SAID CONFINED SPACE DURING THE PERIOD OF SAID POLYMERIZATION AND DURING ANY DISTILLATION OF UNREACTED MONOMERS FROM THE POLYMERIZATE DISPERSION, WHEREBY A POLYMERIZATE IS RECOVERED WITH LOW POLYMER DEPOSITS.
