✦ Synopsis

This paper presents results on the photo-induced grafting of poly(methyl methacrylate) onto poly[bis(4-isopropylphenoxy)phosphazene], using benzophenone as photoinitiator. The formation of polyphosphazene-g-poly(methyl methacrylate) copolymers was followed by FTIR-ATR spectroscopy, and the products were characterized by contact angle and DSC measurements. Among the parameters affecting the photografting, irradiation time and the ratio methanol/unsaturated monomer used in the grafting experiments are of particular importance.
