Abstract
A novel polyampholyte P(DMAPMA-co-HEA)-CA was prepared by the quaternization of chloroacetic acid (CA) to P(DMAPMA-co-HEA), which was synthesized by the copolymerization of 2-hydroxyethyl acrylate (HEA) and N-(3-dimethylaminopropyl)maleamic acid (DMAPMA). The isoelectric point (IEP) of P(DMAPMA-co-HEA)-CA was studied by titration, and the salt resistance of P(DMAPMA-co-HEA)-CA expressed by viscosity was determined in sodium chloride solution by Ubbelohde viscometer. The results show that P(DMAPMA-co-HEA)-CA possesses excellent salt resistance in sodium chloride solution.
