摘要：

In this paper we report the modification of poly[bis(4-sec-butylphenoxy)phosphazenel by solution grafting of maleic anhydride molecules promoted by radical initiators, m order to develop a new class of functionalized poly(organophosphazenes). Grafting reactions and yields, evaluated by FTIR spectroscopy, are investigated as a function of the different experimental conditions, such as maleic anhydride and benzoyl peroxide concentrations, temperature of the process, and grafting time. The new phosphazene materials show improved adhesion strength on the metal surfaces in the melt state as compared to that of the pristine poly[bis(4-sec-butylphenoxy)phosphazene], which is related to the content of succinic anhydride residues grafted onto the polymer.
