2-(N-phthalimido)ethyl methacrylate was prepared by the reaction of methacrylic acid with N-(2-hydroxyethyl)phthalimide in presence of N,N?-dicyclohexylcarbodiimide. The monomer reactivity ratios for copolymerization reactions of 2-(N-phthalimido)ethyl methacrylate with methyl acrylate, ethyl acrylate, butyl acrylate and styrene, respectively, in solution with azobisisobutyronitrile (AIBN) as initiator, were estimated by nitrogen analysis. The structure of the copolymers was investigated by IR spectroscopy. The Q and e values for 2-(N-phthalimido)ethyl methacrylate were calculated. Some of the synthesized polymers were tested for their antimicrobial activity against bacteria and fungi.

Copolymer Poly

Methacrylates have high glass transition temperature (Tg) values and high thermal stability. A new methacrylate copolymer, poly(4-acetylphenyl methacrylate-co-ethyl methacrylate) (APMA-co-EMA), was synthesized. The thermal behaviors of copolymers were investigated by differential scanning calorimetry and thermogravimetric analysis. They behaved as new single polymers with singleTg’s and the thermal stability of the copolymers increased with increasing 4-acetylphenyl methacrylate (APMA) fraction, leading to the manufacture of copolymers with desiredTgvalues. Structure and composition of copolymers for a wide range of monomer feed ratios were determined by Fourier transform infrared (FT-IR) and1H-nuclear magnetic resonance (1H-NMR) spectroscopic techniques. Copolymerization reactions were continued up to 40% conversions. The monomer reactivity ratios for copolymer system were determined by the Kelen-Tüdös (ra(APMA)=0.81;rb(EMA)=0.61) and extended Kelen-Tüdös (ra=0.77;rb=0.54) methods and a nonlinear least squares (ra=0.74;rb=0.49) method.
