Calibration of gel permeation chromatography was carried out to determine molecular weight and molecular weight distribution of the side-chains and homopolymer formed during grafting of cellulose acetate with acrylamide monomer using accelerated electrons. Polyacrylamide in side-chains and in homopolymer was found to be of very high molecular weight; the grafting event was found to be as low as 1–10 polyacrylamide chains per 103 cellulose acetate chains.
