## Abstract A phthalimido group containing methacrylate based monomer 2‐(__N__‐phthalimido)ethyl methacrylate (NPEMA) was synthesized by reacting 2‐(__N__‐phthalimido)ethanol (NPE) with methacryloyl chloride. NPE was prepared by reacting phthalic anhydride dissolved in dimethyl formamide (DMF) with
Free-radical copolymerization of n-butyl methacrylate ( B ) and methacrylamide ( M ) was carried out in the presence of 2,2'-azobisisobutyronitrile ( AIBN ) in dimethyl formamide (DMF) at 60°C. The percentage composition of the copolymers was established by elemental analysis. The reactivity ratios
