This paper deals with (maleic anhydride)‐grafted polypropylene (MAH‐ g ‐PP) and wood flour reinforcement and their effects on the dynamic, mechanical, morphological, and rheological properties of waste polypropylene (PP) composites. MAH‐ g ‐PP was used as a compatibilizer to improve the physical interaction between the filler and matrix. The composites were prepared by using a twin‐screw extruder followed by injection molding. Thermal stability and mechanical properties of the compatibilized system increased as compared to their values for the uncompatibilized system. Also, nearly 60% and 30% loss was found for mechanical properties and weight loss, respectively, in a biodegradability study. J. VINYL ADDIT.
