INTRODUCTION
Functionalization of polypropylene (PP), through the grafting of unsaturated monomers such as maleic anhydride (MAH) in the presence of organic peroxide as a free radical initiator, has already received much attention. The functionalized PP can have many applications [1, 2]. Solution [3], melt [4-6] and solid-state processes [7, 8] have been successfully used for the preparation of functionalized PP. Among them, the melt process has widely been used in the industry owing to its economic and operational advantages. However, a major problem this process faces is the PP chain scission. Recently, new efforts have been made toward reducing PP chain ...
