Blends of polypropylene (PP) with compatibilized and uncompatibilized plasticized potato starch (PPS) have been prepared using an injection molding machine. Glycerol was used as a plasticizer and variable amounts of plasticized potato starch were processed in the presence of polypropylene-graft-maleic anhydride (PP-g-MA) as the compatibilizer. The addition of PPS was found to be directly proportional to the Young’s modulus and inversely related to the tensile strength and elongation at break. However, tensile properties were observed to improve on addition of PP-g-MA to the blends due to improved interfacial adhesion between PPS and PP as shown by the SEM micrographs. The percentage of water gained and weight loss of the PCPS/PP blends were lower than the PPS/PP blends indicating good interfacial adhesion. The plants germinated and grew freely indicating that no harmful effects on the plants due to biodegradation products.
