Procedimiento para la preparación de copolímeros de ésteres vinílicos de ácidos grasos mediante polimerización iniciada en los radicales de a) uno o varios ésteres vinílicos de ácidos carboxílicos con 16 a 22 átomos de carbono y b) uno o varios ésteres vinílicos de ácidos carboxílicos con 2 a 15 átomos de carbono, en el que uno o varios ésteres vinílicos a) y uno o varios ésteres vinílicos b) se aportan dosificadamente durante la polimerización, caracterizado por que durante la polimerización se reduce la tasa de dosificación de ésteres vinílicos a) o la tasa de dosificación de ésteres vinílicos b) y se aumenta la tasa de dosificación del otro de los dos ésteres vinílicos a) o b). 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.
