2-(N-Phthalimido)ethanol (NPE) was prepared by reacting phthalic anhydride with ethanolamine in dimethy formamide medium. The NPE thus obtained was reacted with methacryloyl chloride in the presence of triethylamine to form the monomer, 2-(N-Phthalimido)ethyl methacrylate (NPEMA). Free radical polymerization technique was used to synthesize the homopolymers and copolymers of different composition of NPEMA and styrene in 2-butanone solution at 70 • C ± 1 • C using benzoyl peroxide as initiator. The monomer and the polymers were characterized by IR and 1 H-NMR techniques. The molecular weights (M w andM n ) and polydispersity index of the polymers were determined using gel permeation chromatography. Thermogravimetric analysis of the polymers were carried out in air. The solubility of the polymers were also studied. The composition of the copolymers was inferred from the 1 H-NMR data obtained. The reactivity ratios of the monomers were determined by the application of FinemanRoss and Kelen-Tüdös methods. ORDER REPRINTS 68SENTHILKUMAR ET AL.
