Abstract: 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.

Abstract: The invention relates to an electrode coating for a lithium-ion battery, containing copolymer C or the salt thereof, copolymer C being synthesized by polymerizing a combined total of more than 70 wt % of vinyl-functional cyclic carbonate and one or more monomers from the group comprising acrylic acid and the derivatives thereof, the percentage by weight of vinyl-functional cyclic carbonate in relation to the weight of all monomers used being 5-90%.

Abstract: The invention relates to a polymer composition P containing: 100 parts-by-weight of polymer 1, which polymer is at least 50 g/l water-soluble at 25° C. and 1 bar, and can be produced via radical-initiated polymerisation of more than 95 wt. % of monomers from the group of acrylic acid, methylacrilic acid, or the esters thereof, acrylonitrile and vinylester, and, optionally, via subsequent alkaline hydrolysis; 10 to 200 parts-by-weight of polymer 2, which polymer is at least 10 g/l water-soluble at 25° C. and 1 bar, has a viscosity of a 1 wt. % aqueous solution at 25° C. and 1 bar at a shear rate of 10/s>1.0 Pas, and at a shear rate of 120/s<0.7 Pas, from the group of polysaccharides, celluloses or the carboxymethyl-, methyl-, hydroxyethyl- or hydroxypropyl derivatives thereof; and 20 to 300 parts-by-weight of polymer 3, which polymer is at least 10 g/l water-soluble at 25° C. and 1 bar, and can be produced via radical-initiated polymerisation of more than 30-95 wt.
