Abstract:
A method for producing a release agent dispersion capable of being used for glue-resistant layering on a substrate, said method comprising producing release effective copolymers by radical polymerization in an aqueous dispersion in acidic or neutral medium from the following monomers:a) 10-90 parts by weight, relative to the total weight of the monomers, of at least one release effective component selected from the group consisting of one or more maleic acid monoamides or maleic acid monoesters or the corresponding fumaric acid derivatives, having carbon-hydrogen groups with chain lengths of 12-32 carbon atoms; b) 15-85 parts by weight, relative to the total weight of the monomers, of at least one comonomer selected from the group consisting of styrene, olefin, vinyl ether, vinyl ester, and (meth)acrylate derivatives and mixtures of these comonomers, wherein the proportion of said comonomer or mixtures thereof occurs in an amount that suffices for a copolymerization with the maleic (fumaric) acid derivatives and can also contain release effective monomers; and c) 0.5-20 parts by weight, relative to the total weight of the monomers, of polyunsaturated compounds or monomers cross-linked over functional groups.
