Microcrystalline cellulose (MCC) \ Polypropylene (PP) \ composites were prepared containing polypropylene–graft–maleic anhydride (PP–g–MA) as compatibilizer. The weight ratio of the cellulosic materials to polymer matrix was 40:60 (w:w). The obtained results showed that tensile, flexural and impact strengths of the composites were significantly enhanced with addition of MCC, as compared with pure PP and composites without MCC. The effect of MCC on impact was minimal compared to the effects of PP–g–MA content. Scanning electron microscopy has shown that the composite, with compatibilizer, promotes better fiber–matrix interaction. In all cases, the degradation temperatures shifted to higher values after addition of PP–g–MA. The maximum improvement on the thermal stability of the composites was achieved when 5% PP–g–MA was used. However, the increase in MCC content substantially reduced the thermal stability. This work showed that MCC along with wood flour could be effectively used as reinforcing agent in thermoplastic matrix<\div>
