| abstract |
The present invention relates to an ampholytic polymeric system obtainable by a process comprising the copolymerization of (i) a monomer according to Formula (1), (ii) an ethylenically unsaturated cationic monomer and (iii) a (co)polymer comprising an ethylenically unsaturated anionic monomer which comprises a sulfonate group: (1) wherein X is O or NR 2 , R 1 and R 2 are independently selected from the group consisting of hydrogen and C1-C6 alkyl groups or wherein R 1 and R 2 form together a (CR 1 R 2 )n- chain, wherein n is 3 to 12, and wherein R 3 is independently selected from the group consisting of hydrogen and CH 3 . The present invention further relates to the use of ampholytic polymeric system in separation processes. |
