ABSTRACT
Date seed particles (DSP) filled polypropylene composite were prepared by compounding and pressing technique. The average particle sizes of date seeds particles used were 63, 125, 250, 500 and 750 μm. The
effects of filler particle size and alkaline treatment on moisture content (%) and soil burial degradation properties of Date seed particles (DSP) filled polypropylene composites were investigated. The result shows that moisture content (%) increases with increase in filler particle size and decreased when sodium hydroxide concentration increases. Soil burial degradation (%) of the composites was studied using percentage weight loss. From the results this property was found to be increasing with the increase in filler particle size and decreased with increase in sodium hydroxide concentration.Keywords: Polypropylene, Date seed particles (DSP), Particle size, Sodium hydroxide treatment, Moisture content and Soil burial degradation properties
