Procedure
An ethylene/vinyl chloride/vinyl acetate copolymer dispersion was prepared analogously to EP 76 511. First, a mixture of 1,700 g of vinyl acetate and 6,800 g of vinyl chloride was introduced into a tank and 2,000 g of demineralized water and 3,500 g of a 20% solution of a polyvinyl alcohol with a saponification number of 140 and a viscosity of 5 mPas (4% strength aqueous solution at 20° C., according to Hoppler) were introduced into a boiler of 16 liter capacity. A vacuum was then applied which was interrupted with nitrogen and the boiler was then evacuated again, the stirrer driven at 250 min-1, and the contents were heated to 50° C.
