  • Patent number: 5340441
    Abstract: Cationic copolymers which are insoluble in water based on acrylamide, and a cationic monomer of general formula (I) ##STR1## in which R and R.sub.1, identical or different, represent a hydrogen atom or a methyl group, X represents an oxygen atom or an NH radical and n represents 2 or 3, containing in molar proportions 5 to 30% of cation units and cross-linked with 0.01% to 0.4% in molar proportions relative to the previous monomers of bisacrylamidoacetic acid and with about 0.01% to 0.1% in molar proportions relative to the monomers of bisacrylamidoacetic acid, self-reversible dispersions containing them and use in coating in the paper industry.
