Co-polymers of N-phenyl methacrylamide and glycidyl methacrylate of different compositions were synthesized by free radical solution co-polymerization of the monomers in dimethylformamide using benzoyl peroxide as the initiator at 70 • C. Solubility of the co-polymers was tested in various solvents. The molecular structure of the co-polymers was elucidated by infrared and proton nuclear magnetic resonance spectroscopy. The composition of the co-polymers was determined from their 1 H-NMR spectra by using the intensities of aliphatic and aromatic protons present in the co-polymer. The Finemann-Ross and Kelen-Tüdos models have been employed to determine the reactivity ratios of the monomers. The intrinsic viscosities of the co-polymers of GMA and PMA were determined using a Ubblehode viscometer. The thermal transitions of the co-polymers were determined using differential scanning calorimetry and thermogravimetric analysis.

Abstract-Co-polymerization of BPM with methyl methacrylate (MMA) has been carried out in methyl ethyl ketone (MEK) by free radical solution polymerization at 70 ± 1 • C utilizing benzoyl peroxide (BPO) as initiator. Poly(BPM-co-MMA) co-polymers were characterized by FT-IR, 1 H-NMR and 13 C-NMR spectroscopy. The molecular weights (M w and M n ) and polydispersity indices (M w /M n ) of the polymers were determined using gel permeation chromatograph. The glass transistion temperatures (T g ) of the co-polymer increases with MMA content. Thermogravimetric analysis of the polymers performed in nitrogen shows that the stability of the co-polymer increases with an increase in BPM content. The solubility of the polymers was tested in various polar and nonpolar solvents. Co-polymer compositions were determined by 1 H-NMR spectroscopy by comparing the integral peak heights of well separated aromatic and aliphatic protons peaks. The monomer reactivity ratios were determined using Fineman-Ross (r 1 = 1.70 ± 0.054, r 2 = 0.065 ± 0.004), Kelen-Tudos (r 1 = 1.73 ± 0.035, r 2 = 0.077 ± 0.008) and extended Kelen-Tudos methods (r 1 = 1.866 ± 0.100, r 2 = 0.069 ± 0.008).

Abstract. The acrylate monomer, 7-acryloyloxy-4-methyl coumarin (AMC) has been synthesized by reacting 7-hydroxy-4-methyl coumarin, with acryloyl chloride in the presence of NaOH at 0-5°C. Copolymers of 7-acryloyloxy-4-methyl coumarin (AMC) with vinyl acetate (VAc) were synthesized in DMF (dimethyl formamide) solution at 70±1°C using 2,2′-azobisisobutyronitrile (AIBN) as an initiator with different monomer-to-monomer ratios in the feed. The copolymers were characterized by Fourier transform infra red (FTIR) spectroscopy. The copolymer composition was evaluated by 1 H-NMR (proton nuclear magnetic resonance) and was further used to determine reactivity ratios. The monomer reactivity ratios for AMC (M1)-VAc (M2) pair were determined by the application of conventional linearization methods such as Fineman-Ross (r1 = 0.6924; r2 = 0.6431), Kelen-Tüdõs (r1 = 0.6776; r2 = 0.6374) and extended Kelen-Tüdõs (r1 = 0.6657; r2 = 0.6256). Thermo gravimetric analysis showed that thermal decomposition of the copolymers occurred in single stage in the temperature range of 263-458°C. The molecular weights of the polymers were determined using gel permeation chromatography.The homo and copolymers were tested for their antimicrobial properties against selected microorganisms.
