The synthesis of two new methacrylate esters containing morpholine and pyrrolidine group are described. The monomers produced from the reaction of corresponding morpholino chloroacetamide and pyrrolidino chloroacetamide with sodium methacrylate were polymerized in DMSO solution at 65degreesC using AIBN as an initiator. The monomers and their polymers were characterized by Fourier transform infrared (FTIR), H-1- and C-13-NMR spectroscopy. The glass transition temperature of the polymers were investigated by DSC and thermal decomposition activation energies were calculated by the Ozawa method using the SETARAM Labsys thermogravimetric analysis (TGA) thermobalance, respectively. By using gel permeation chromatography, weight average ((M) over bar (W)) and number average ((M) over bar (n)) molecular weights and polidispersity indices of the polymers were determined.
