Maleic anhydride (MAN) is an excellent monomer which can provide reactive anhydride or carboxylic groups, with nucleophilic molecules. Recently , extensive studies have beenperformed on the radical copolymerization of MAN with other monomer and the self assembly of their copolymers [1].results show that maleic anhydride (MAN) have a low tendency to homopolymerize. But copolymers by other monomers , can be abtained via radical polymerization.[2].
