2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPS),and maleic acid (MA)copolymerized with different feed ratios using N,N-dimethylformamide as a solvent and benzoyl peroxide (Bz2O2) as an initiator at 70℃.Structure and composition of copolymers for a wide range of monomer feed were determined by elemental analysis (content of N for AMPS-units).Monomer reactivity ratios for AMPS(M1)-MA(M2) pair were determined by the application of conventional lineartion methods such as Fineman-Ross(F-R),Kelen-Tüd(o)s(KT)and Extended Kxtended Kelen-Tüd(o)s(EKT) and a nonlinear error invariable model method using a computer program RREVM.The characterizations were done by Fourier transform infrared spectroscopy (FTIR),differential scanning calorimetry (DSC) thermal gravimetry analysis (TGA),and and Ⅹ-ray diffraction.The antimicrobial effects of polymers were also tested on various bacteria,and yeast.
