Abstract

The synthesis of two new methacrylate esters containing 2-(4-benzyl piperazin-1-yl)-2-oksoethyl and 2-(4-methylpiperidin-1-yi)-2-oksoethyl group are described. The monomers produced from the reaction of corresponding 4-methylpiperidinechloroacetamide and 1-benzylpiperazinechloroacetamide with sodium methacrylate was polymerized in DMSO solution at 65 degreesC using AIBN as an initiator. The monomers and their polymers were characterized by IR, H-1- and C-13-NMR spectroscopy. The glass transition temperature of the polymers were investigated by DSC and the apparent thermal decomposition activation energies (E-d) were calculated by Ozawa method using the SETARAM Labsys TGA thermobalance. By using gel permeation chromatography, weight average ( (M) over barw) and number average ( (M) over baru) molecular weights and polidispersity, indices of the polymers were determined.
