In order to maintain proper  \nprocessing conditions it is necessary after a certain periodof time to eliminate this film either chemically with alkalisor organic solvents,or mechanically by manual operations.This reduces the production capacity,involves consumption ofauxiliary substances and the problem of neutralization of thecleaning products.  \nOnly the following methods of cleaning were found inthe available literature:  by means of alkaline aqueoussolutions,by means of solvents and mechanically·  \nFilm formation and solid sediments are prevented by emulsionpolymerization according to our invention.Steam is introducedto the empty space of the polymerization reactor in such anamount that a supersaturated atmosphere forns and condensationoccurs on the inside of the polyimerization reactor and thefittings.The condensed water dilutes the splashed dropletsof latex and descends with them into the reaction mixture sothat the inside of the polymerization reactor and fittingsremain clean.
