Abstract

Method for the production of polyvinylchloride in aqueous suspension with the recovery of wastes, which provides for the use of a plant for the production of polyvinylchloride which has at least one reactor to convert the vinyl chloride monomer into polyvinylchloride in aqueous suspension and vinyl chloride monomer wastes in the gaseous state, and separating at least part of the water of the aqueous polyvinylchloride suspension as waste water, characterised in that the said waste water is recycled to the reactor(s) during the polymerisation stage. <IMAGE>
