AbstractThe kinetics of radiation graft polymerization of styrene onto cellulose acetate‐butyrate is studied over a range of radiation intensities and monomer concentrations. The reaction is diffusion‐free under the experimental conditions as shown by the independence of the grafting rate on film thickness. The dependence of the grafting rate on monomer concentration increases from 3/2‐order to slightly greater than 5/2‐order with increasing radiation intensity. The dependence of the grafting rate on radiation intensity decreases from 1/2‐order to 0‐order with decreasing monomer concentration. Possible mechanisms for these results are discussed.
