Abstract :In this study, it has been demonstrated that Poly(Eugenol-co-methylmethacrylate-co-hydroxyethylmethacrylate) terpolymers were successfully synthesized by using photopolymerization method. This synthesis was carried out in one step at ambient temperature, benzophenone and triethyl amine was used as the photoinitiator and hydrogen donor, respectively. Methyl methacrylate (MMA), 2-Hydroxyethyl methacrylate (HEMA) and Eugenol (Eg) were used as monomer in photopolymerization. Terpolymers are named as F-BAP1, F-BAP2, F-BAP3 and F-BAP4 according to the ratio of monomers used. Structural characterization and thermal properties of the synthesized terpolymers were carried out by FTIR (Fourier-transform infrared spectroscopy), 1H-NMR (Nuclear magnetic resonance spectroscopy), TG-DTG (Thermogravimetry-Differential Thermogravimetry) and DSC (Differential scanning calorimetry) methods. Characterization of molecular weight distributions were determined by viscometric method. SEM (Scanning electron microscope) was used for surface analysis. According to the data obtained from thermal analysis, two degradation steps are seen in thermograms of the terpolymers except FBAP-2. The maximum degradation temperature of F-BAP 2 is 422 oC, the first degradation temperature of the other terpolymers between 250-280 oC and the second one between 421-427 oC.
