WATER SOLUBLE SALINE AQUEOUS DISPERSIONS OF COPOLYMERS BASED ON CATIONIC MONOMERS, METHOD FOR MAKING SAME AND USES THEREOF

摘要

The invention concerns a water soluble saline dispersion of a copolymer obtained from a composition of water soluble monomers, comprising for 100 mole parts, 0.5 to 65 mole parts of at least a compound (I) and 0.5 to 95 mole parts of at least a monomer (II) and/or diethylaminoethyl (meth)acrylate quaternized with dimethyl sulphate wherein R<1> = H or -CH3; R<2> = -CH3; -C2H5; -C3H7 or -C4H9; and compound (I) is optionally quaternized on one of the nitrogen atoms, which is symbolised by the fact that the R<3>, X<-> and <+> associated with said nitrogen is between square brackets; when compound (I) is quaternized on a single nitrogen, R<3> and X<-> represent the following: (1) R<3> = -CH3 or CH2C6H5; and X<-> = Cl<-> or CH3OSO<->; or (2) R<3> = -(CH2)pCH3 with p an integer from 3 to 11; and X<-> = Br<-> or I<->; when compound (I) is quaternized on both nitrogens, both X<-> can be identical or different and the both R<3>, can be identical or different, in which case (3) R<3> = -CH2-C6-H5; and X<-> = Cl<->; and (4) R<3> = -(CH2)pCH3 with p an integer from 3 to 11; and X<-> = Br<-> or I<->; (5) among the compounds (I) quaternized on both nitrogens and having two different R<3>, if one of the R<3> = CH3, C2H5, or C3H7; and X<-> = Cl<-> of CH3OSO3<->; and the other = -CH2C6H5, the associated X<-> representing Cl<->, or represents -(CH2)pCH3 with p an integer from 3 to 11, The associated X<-> representing Br<-> or I<->; R<8> = H or CH3; A<1> = O or NH; B<1> = -CH2-CH2- or -CH2-CH2-CH2- or -CH2-CHOH-CH2-; R<9> and R<10> = -CH3, -CH2-CH3; R<11> = -(CH2)o -CH3(o = 3 to 9) or benzyl; X<-> = monovalent ion.
