Abstract (en)
[origin: FR2804122A1] An aqueous dispersion, comprises a mono- or di-quaternary amino acrylate-based copolymer. An aqueous dispersion, comprises a hydrosoluble copolymer comprising: (a) a monomer(s) of formula (I), quaternized on one or both of the N atoms (0.5-99.5 mole parts - mol.pts.); (b) a hydrosoluble monomer(s) from those of formulae (II), (III) and (IV) ((IV) is the same as formula (I), but R<3> = CH2, C2H5 or C3H7, and X = Cl or CH3OSO3) and unsaturated carboxylic, sulfuric and sulfonic acids and their derivatives (99.5-0.5 mol.pts.); (c) hydrophobic monomer(s) ( <= 30 mol.pts.); (d) crosslinking monomer(s) ( <= 10 mol.pts.); and (e) amphiphilic monomer(s) ( <= 30 mol.pts.): R<1> = H or CH3; R<2> = CH3, C2H5, C3H7 or C4H9; And either compound (I) is singly quaternized and: R<3> = -CH2(C6H5); and X<-> = Cl<-> or CH3OSO3<->; Or: R<3> = (CH2)pCH3; p = 3-11; and X<-> = Br<-> or I<->; Or compound (I) is doubly quaternized and each R<3> is identical and: R<3> = -CH2C6H5; X<-> = Cl<->; Or: R<3> = -(CH2)pCH3; and X<-> = Br<-> or I<-> Or compound (I) is doubly quaternized and each R<3> is different and: the first R<3> = -CH3, -C2H5 or -C3H7; and X<-> = Cl or CH3OSO3; the second R<3> = CH2C6H5; and X<-> = Cl<->; or the second R<3> = -(CH2)pCH3; and X<-> = Br<-> or I<->; R<8>, R<11> = H or CH3; R<9>, R<10> = H or 1-5C alkyl; A<1> = O or NH; B<1> = CH2CH2, CH2CH2CH2 or CH2CH(OH)CH2; and R<12>, R<13> = H, 1-6C (hydroxy)alkyl, 5-12C cycloalkyl, 6-12C aryl or 7-12C alkylaryl. Independent claims are included for the preparation of these dispersions by radical polymerization of the monomers in the presence of a dispersant polymer.
