✦ Synopsis
The radiation-induced grafting to cellulose of styrene, methyl methacrylate, Vinyl acetate, %vinylpyridme, and 4vinylpyridine in methanol has been studied. All monomers exhibit appreciable grafting at room temperature in either vacuum or air for total doses up to 10 Mrad and a t dose rates as high as 1.4 Mrad/hr. in a spent fuel or 'OCo facility. The magnitude of the grafting depends upon both the total dose and dose rate. Under certi~in experimental conditions, the grafting experiences a maximum which has been a& tributed to the Trommsdorff effect. A novel mechanism involving charge-transfer bond formation is proposed to account for the observed data in the grafting reactions.
