Abstract :

The Acrylamide based monomer, N–tert–butylacrylamide (NTB) and 2–methyl–N–1, 3–thiazole–2–acrylamide (TMA) was synthesized and characterized by NMR spectroscopy. Copolymerization of NTB with TMA in different feed ratio was carried out in 1, 4–dioxane at 60±1^oC using AIBN as initiator. The resulting copolymers were characterized by ¹H–NMR spectroscopy and the copolymer compositions were determined by ¹H–NMR data. Fineman–Ross, Kelen–Tudos and extended Kelen–Tudos methods were employed to calculate the reactivity ratios of monomers. Mean sequence lengths of copolymers were estimated from r₁ and r₂ values. Thermogravimetric analysis of the polymers reveals that the thermal stability of the copolymers increases with increases in the mole fraction of NTB in the copolymers. The obtained copolymers were tested for their antimicrobial activity against selected micro–organisms.
