dc.description.abstractIn this study, a Ultraviolet-radiated curable resin from palm oil was prepared by modifying palm oil with glycerol and glycidyl methacrylate (GMA). In the preliminary study, different parameters such as the amount of catalyst needed, reaction temperature and time for this chemical modification had been studied. From the Fourier Transform Infrared (FTIR) analysis, GMA was proved to be chemically attached to the monoglyceride (MG), an increment at peak 1630 cm-1 in FTIR spectrum was observed when more GMA was used in the chemical modification. In the subsequent study, the effect of different glycerol/palm oil (MG) to GMA/MG ratio in the preparation of MG-GMA resin was studied. It was noticed that hydroxyl number of MG increased as more glycerol was used in the glycerol/palm oil mixture in alcoholysis process. This indicated that most of the hydroxyl groups were contributed by MG as shown by capillary gas chromatography (GC) results. The weight average molecular weight (Mw) of the resin increased as the ratio of GMA/MG was increased to a threshold point after which it decreased. This phenomenon was due to homopolymerization of GMA monomer during the treatment of MG with GMA. A similar trend was also observed in the result of viscosity. The gel content of the cured MG-GMA film was more than 98%. The hardness, cross hatch adhesion and thermal stability of the MG-GMA film was influenced by the amount of GMA used as well as the glycerol used in MG preparation. Both differential scanning calometry (DSC) and thermogravimetry analysis (TGA) showed that the increment of GMA amount in MG-GMA resin had improved the thermal stability of the UV-cured films. Thermal decomposition kinetics of MG-GMA film discovered that Friedman method showed a good agreement with that of Ozawa-Flynn-Wall (O-F-W) method. Real time FTIR (RT FTIR) curing kinetics of MG-GMA resin showed that double bonds conversion and polymerization rate of the resin were affected by the concentration of unsaturation groups.en_US
