Radiation grafting is a convenient one-step method for modifying the properties of polymers1,2. Both ultraviolet light3–7 and ionizing radiation8–12 are useful initiators for the process, however the latter method possesses advantages, especially with cobalt-60 type ionizing sources, because of the penetrating effect of the gamma rays. There are a number of procedures using ionizing radiation which can lead to grafting. Of these, the mutual or simultaneous technique is generally the most useful and will be discussed in depth in this article. Any method for accelerating the procedure is valuable, especially for those backbone polymers which are especially sensitive to ionizing radiation. In such instances, it is preferable to use the lowest total radiation dose to achieve a particular percentage graft.
