Abstract The free‐radical copolymerization of (2‐oxo‐2‐ tert ‐butylamino)ethylene methacrylate (TBAMA) with styrene was carried out in 1,4‐dioxane at 65 ± 1 °C. The copolymers were characterized by FTIR, 13 C‐NMR and 1 H‐NMR spectroscopic methods. The copolymer compositions were determined by elemental analysis. The weight‐average and number‐average molecular weights of the copolymers were obtained by gel permeation chromatography (GPC). Thermal properties of the polymers were also studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The monomer reactivity ratios were calculated according to the general copolymerization equation using Kelen–Tüdõs and Fineman–Ross linearization methods. The thermal decomposition activation energies of the polymers were evaluated by the multiple heating rate kinetics (MHRK) method. The antibacterial and antifungal effects of the copolymers were also investigated on various bacteria and fungi. Copyright © 2004 Society of Chemical Industry
