Abstract
Terpolymerization of 2-ethoxyethyl methacrylate (2-EOEMA), styrene (St) and maleic anhydride (Ma) initiated by benzoyl peroxide was carried out in acetone as common solvent for three monomers. The structure and composition of terpolymer were determined by FTIR spectroscopy by recording analytical absorption bands for St (3002 cm−1), Ma (1781 cm−1) and 2-EOEMA (1261 cm−1) units, respectively. The reactivity ratios for the monomers were calculated according to the general copolymerization equations following the Finnemann-Ross and Kelen-Tudos models. The results show that terpolymerization were carried out through primary “complex” mechanism at near-binary copolymerization of [St...Ma] complex with 2-EOEMA. Structure of the resulting terpolymer illustrated by1H-NMR and differential scanning calorimeter showed reduction inT g value.
