The number of anionic monomer content of each sample is known as the anionic degree. The anionic degree obtained from 13 C-NMR peak integration and titration methods are given in Table 1 . The 13 C-NMR analysis was carried out for calculation of copolymer composition using the well-resolved carbonyl peaks due to different chemical shifts of AM and AMPS functional carbonyl groups.
