Polypropylene (PP) has poor adhesion to metals and other surfaces for its chemical structure. Hence, chemical * %. /01 # modification of PP is necessary for metal surface coating application. In this research, grafting of maleic anhydride (MA) onto co (propylene-b-ethylene) in the presence of a dicumyl peroxide (DCP) was accomplished in a single screw extruder. Characteristics of the modified polymer were determined by Infra-red Spectroscopy (IR), Scanning Electron Microscopy (SEM), and adhesion test. Maximum grafting of MA was found to be 1.2832% for 1.5 pph of MA. Adhesion test showed that the samples containing 1 pph of MA (degree of grafting is 0.5816%) had better adhesion to steel surface (17.25 kgf).
