INTRODUCTION
The grafting of polar monomers onto saturated polymers has been performed intensively for a number of applications. One of the most frequently used monomers is maleic anhydride (MA), owing to the high reactivity of anhydride group in successive reactions. A number of reactions have been proposed for the grafting of MA (1). The initiation of the grafting can be either by peroxide decomposition or by thermo-mechanical radical formation. The radicals abstract hydrogen from the polymer chain. MA molecules may add to these macroradicals, thus forming MA radicals covalently bonded to the polymer (1). During the grafting of MA, ...
