An overview of the grafting reactions of organic substrates onto poly(organophosphazenes) is presented. It was found that the type of phosphazene substrate used in the reactions, the swelling properties of the polymeric films, the characteristics of the photoinitiators and the composition of the reaction media are the major factors that influence the light-induced grafting of organic macromolecules onto polyphosphazene matrices. When the thermal grafting of maleic anhydride onto poly(organophosphazenes) is considered, the nature of the polymer, the reaction temperature, and the peroxide concentration are of importance.

Abstract
An overview of the grafting reactions of organic substrates onto poly(organophosphazenes) is presented. It was found that the type of phosphazene substrate used in the reactions, the swelling properties of the polymeric films, the characteristics of the photoinitiators and the composition of the reaction media are the major factors that influence the light-induced grafting of organic macromolecules onto polyphosphazene matrices. When the thermal grafting of maleic anhydride onto poly(organophosphazenes) is considered, the nature of the polymer, the reaction temperature, and the peroxide concentration are of importance.
