Subject-matter of the invention are processes for preparing fatty acid vinyl ester copolymers by radically initiated polymerization of a) one or more vinyl esters of carboxylic acids having 16 to 22 carbon atoms and b) one or more vinyl esters of carboxylic acids having 2 to 15 carbon atoms, with one or more vinyl esters a) and one or more vinyl esters b) being metered in during the polymerization, characterized in that during the polymerization either the metering rate of vinyl ester a) or the metering rate of vinyl ester b) is reduced and the metering rate of the other of the two vinyl esters, a) or b), is increased.
