【 摘 要 】

Acrylated epoxidized palm oil (AEPO) prepared by the reaction of epoxidized palm oil (EPO) with acrylic acid, triethylamine initiator and hydroquinone inhibitor prepared at various temperature and reaction times. The unsaturated polyester (UPE) resin was blended thoroughly with 10 wt% of the modified palm oil at room temperature, and thermally cured at 100 °C and post-cured at 160°C. The prepared palm oil derivative was characterised by using Fourier Transform Infrared (FTIR) and the test proved the formation of acrylate functional group with characteristic absorbance at 1600-1600 cm-1 that indicates C=C functional group of the acrylate. The polymer blend tensile strength of the palm oil acrylate processed at 110°C for 16 hours (M2) showed reduction from 25.56 MP to 13.26 MP (48%), reduction in tensile modulus from 1.47 GPa to 1.18 GPa (19.7%) and the highest impact strength among the four acrylates of polymer blend is 21.97 J/m from palm oil acrylate processed at 105°C for 16 hours (M3). However, polymer blend from M2 acrylate showed increased in elongation at break from 2.805 % to 3.493 % (24.5 %) compared to neat unsaturated polyester and it outweighed reduction in tensile and impact of the polymer blend.
