Abstract
2-N-Phthalimido-2-methyl propan-1-ol was prepared by refluxing phthalic anhydride dissolved in dimethyl formamide with 2-amino-2-methyl propan-1-ol. The monomer, 2-N-phthalimido-2-methyl propyl methacrylate was synthesized by reacting 2-N-phthalimido-2-methyl propan-1-ol dissolved in ethyl acetate with methacryloyl chloride in the presence of triethylamine. Free radical polymerization technique was used to synthesize the homo and copolymers of different feed composition of 2-N-phthalimido-2-methyl propyl methacrylate and methylmethac-rylate in ethyl acetate solution using benzoyl peroxide as a free radical initiator at 70°C. The IR and 1H-NMR spectroscopic techniques were used for the characterization of the polymers. The composition of the copolymers were determined by 1H-NMR analysis. The reactivity ratios of the co-monomers were evaluated according to Fineman-Ross and Kelen-Tudos methods.Thermal analysis of the polymers were carried out using TGA-DTG method. Gel permeation chromatography was used for d...
