Synthesis and characterization of novel methacrylate copolymers based on sulfonamide and coumarine: Monomer reactivity ratios, biological activity, thermal stability, and optical properties
The free radical copolymerization of 2‐oxo‐2‐[(4‐sulfamoylphenyl)amino]ethyl‐2‐methylpropenoate (SAEMA) with 4‐methyl‐2‐oxo‐2H‐chromen‐7‐yl‐2‐methylpropenoate (MCMA) has been carried out in 1, 4‐dioxane at 65 °C ± 1 °C and the copolymers were analyzed by Fourier‐transform infrared, 1H‐NMR, 13C‐NMR and gel permeation chromatography. 1H‐NMR and elemental analysis was used to determine the molar fractions
