in the reported experiments, ce**i**v-induced grafting of methyl methacrylate and acrylonitrile on cotton fibers crosslinked with dimethylol ethylene urea, dimethylol dihydroxyethylene urea, and dimethylol carbamate was investigated. the graft yields obtained with crosslinked cotton were significantly lower than the untreated cotton, irrespective of the crosslinking agent and the monomer used however, the extent and rate of grafting depended upon the degree of crosslinking and the nature of monomer. based on the magnitude of grafting and ce**i**v consumption during grafting and oxidation of the untreated and crosslinked cottons, the different reactions occurring during grafting of vinyl monomers on these modified cottons were elucidated. 37 refs
