The aqueous copolymer dispersion was prepared in an analogous manner to example 11, but by carrying out the polymerization with a modified monomer mixture at an ethylene pressure of 5 atmospheres. A mixture of 764 g of vinyl acetate and 76 g of monochloroacetic acid vinyl ester was added to the polymerization mixture at room temperature and after the polymerization had started a mixture of 6880 g of vinyl acetate and 688 g of monochloroacetic acid vinyl ester was introduced by pumping over a period of 6 hours. The dispersion obtained of a copolymer of vinyl acetate/monochloroacetic acid vinyl ester/ethylene had a solids content of 51% by weight and a latex viscosity of 23 poises.
