Abstract—Polypropylene (PP) was functionalized with maleic anhydride (MAH) in the presence of dicumyl peroxide (DCP) via melt grafting in a batch mixer, where the maleic anhydride and peroxide concentrations were varied. The effect of concentration of monomer and initiator on the degree of functionalization and properties of the products was investigated by FT-IR spectroscopy, contact angle measurement, thermal analysis and titration. It was found that the degree of functionalization depends on the initial concentration of monomer and initiator that used in reaction. Finally a mechanism of melt grafting MAH onto PP proposed on the basis of our experimental results and other experimental finding published in the literature. |
