摘要

Water-insoluble cationic copolymers based on acrylamide and a cationic monomer of general formula (I) …… in which R and R1, which are identical or different, denote a hydrogen atom or a methyl group, X denotes an oxygen atom or an NH radical and n denotes 2 or 3, containing, in molar proportions, from 5 to 30 % of cationic units and crosslinked with from 0.01 % to 0.4 % in molar proportions in relation to the above monomers of bisacrylamidoacetic acid and with approximately from 0.01 % to 0.1 % in molar proportions in relation to the monomers of bisacrylamidoacetic acid, self-reversible dispersions containing them and application in coating in paper manufacture.
