Gamma-radiation, free-radical graft

Mechanistically the processes Involved in grafting styrene in a polar solvent to cellulose with ionizing radiation and sensitized UV are analogous. Each process Is predominantly free radical In nature with a possible contribution from energy transfer processes. In the gamma ray system grafting sites in the cellulose (CelloH) are formed by the sequence of processes shown in Equations 1 to 3 with methanol as representative solvent.
