Popis:	A new thermoplastic blend was developed using polypropylene (PP) with natural rubber (NR) as the base material. The natural filler is added to enhance the properties of PP/NR blend. The first series was to compare the properties of PP/NR blend with different filler loading. Second series was to investigate the effect of dynamic vulcanization on the properties of PP/NR blend filled with Cyperus Odoratus with the intention of improving the blend properties. Process development, tensile properties, thermal analysis, FTIR analysis and morphological characterization of blends were investigated with the variation of the conditions of the blend. The increasing filler loading decrease the tensile properties of the PP/NR blend and it shows in the morphology study of the blend. Dynamic vulcanization of the blend resulted in improved tensile and thermal properties compared to unvulcanized counterpart. This result is confirmed by the SEM study that showed better dispersion of NR in the PP matrix and improved adhesion between the two phases.
