| titleOfInvention | Salt-free aqueous dispersions of water soluble (co)polymers based on cationic monomers, method for making same and uses thereof |
| abstract | The present invention relates to salt-free aqueous dispersions of water-soluble copolymers obtained from monomer compositions containing from 0.5 to 99.5 molar parts of one or more monomers of formula (I) per 100 molar parts:n n n [Formula I]n n n n n n n n Wherein R 1 = H or -CH 3 ; R 2 = -CH 3 ; -C 2 H 5 ; -C 3 H 7 or -C 4 H 9 ;n n n Compound (I) is optionally quaternized on one of the nitrogen atoms, symbolized by the fact that R 3 , X − and + associated with that nitrogen are between square brackets; When compound (I) is quaternized only on one nitrogen, R 3 and X − represent the following:n n n (1) R 3 = -CH 2 C 6 H 5 ; X - = Cl - or CH 3 OSO 3 - or; Or (2) R 3 =-(CH 2 ) p CH 3 (p is an integer from 3 to 11); X - = Br - or I - Lim;n n n When compound (I) is quaternized on both nitrogen, both X − may be the same or different and both R 3 may be the same or different, in which case (3) R 3 = —CH 2 —C 6 H 5 ; X - = Cl -, or; (4) R 3 =-(CH 2 ) p CH 3 (p is an integer from 3 to 11); X - = Br - or I -, and; (5) from the quaternization is Compound (I) having different two R 3 on both nitrogen, one of R 3 = -CH 3, a -C 2 H 5 or -C 3 H 7 of, X - = Cl - Or CH 3 OSO 3 − , the other = —CH 2 C 6 H 5 , and X − related to the other represents Cl − , or — (CH 2 ) p CH 3 (p is 3 to 11). an integer), X associated with it - represents a) - is Br - or I. |
