Photolytic grafting

Graft polymerization can also be achieved by irradiation with ultraviolet radiation, often in the presence of a photosensitizer such as benzophenone or benzoin [Guthrie et al., 1979 Tazuke and Kimura, 1978], Photolytic grafting is similar to radiation grafting, except that the depth of penetration by UV is far less than by ionizing radiation.
