The free radical copolymerization of glycidyl methacrylate (GMA) and octadecyl acrylate (ODA) was carried out at 70 degrees C in solution using toluene as solvent and 2,2'-azobisisobutyronitrile (AIBN) as initiator. The copolymer compositions were determined using H-1 NMR spectroscopy. The monomer reactivity ratios were computed using five linear methods at low conversions, i.e. Mayo-Lewis (ML), Fineman-Ross (FR), inverted Fineman-Ross (IFR), Ezrielev-Brokhina- Roskin (EBR) and Kelen-Tudos (KT). The reactivity ratios resulted from different methods are in agreement with each other and showed higher reactivity for GMA monomer in comparison with ODA monomer (FR: r(G) = 1.29 and r(O) = 0.68). Crosslinked GMA-ODA copolymers were also prepared using ethylene glycol dimethacrylate as a crosslinker. Thermal properties and swelling behaviors of crosslinked copolymers in different polar and nonpolar solvents were evaluated. GMA incorporation in the crosslinked copolymers improved T-g values, while decreased T-m quantities and swelling in nonpolar solvents. The swelling values are in the acceptable range and the prepared functional crosslinked copolymers can be used for nonpolar solvents absorbency applications.
