Claims16
A method of making emulsions comprising polymerizing vinyl acetate and N vinyllactams in the presence of a polyether, and using the copolymers as stabilizing agents for emulsions.
The method according to 1, where the water-soluble or water-dispersible copolymers have K values in the range from 10 to 60, measured in a 1% strength by weight ethanolic solution.
An emulsion comprising, as stabilizing agents, water-soluble or water-dispersible copolymers which are obtained by polymerization of vinyl acetate and N vinyllactams in the presence of a polyether.
