Abstract
2‐Acrylamido‐2‐methyl‐1‐propanesulfonic acid (AMPS), and crotonic acid (CrA) copolymerized with different feed ratios using N,N‐dimethylformamide as a solvent and benzoyl peroxide (Bz2O2) as an initiator at 70°C. 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)‐CrA (M2) pair were determined by the application of conventional linearization methods such as Fineman‐Ross (F‐R), Kelen‐Tüdös (KT) and Extended Kelen‐Tüdös (EKT) and a nonlinear error invariable model method using a computer program RREVM. The characterizations were done by Fourier transform infrared spectroscopy (FTIR), 1H‐and 13C‐NMR spectroscopy, differential scanning calorimetry (DSC) thermal gravimetry analysis (TGA), scanning electron microscopy (SEM), and X‐ray diffraction. The antimicrobial effects of polymers were also tested on various bacteria, and yeast.
