Abstract
Oil palm empty fruit bunch (EFB), nowadays, has not been fully utilised economically and is always subjected to environmental concern, whereas its handling in the palm oil mill also consumes unproductive cost and energy. In this work oil palm empty fruit bunch filled polypropylene composites were prepared using solution technique and reactive processing in a screw extruder. Results indicate that in the first technique, tensile strength of the composites increases with increasing oil palm empty fruit bunch loading up to 20% (by weight) in the presence of 3% (by weight) of acrylic acid and 0.01 mol ratio of dicumyl peroxide. However the elongation at break shows decreasing trend. Similar observation was also obtained for composites prepared in a single screw extruder. Results from SEM, GPC and IR spectra show that better compatibility between oil palm empty fruit bunch and polypropylene was achieved in the presence of acrylic acid.
