The invention provides an improved cellulosic ester or ether product with an ester or ether degree of substitution (D.S.) of between 2.0 and about 2.9 which is derivatized or further reacted by reaction with an acrylamide reagent to substitute to a pendent acrylamide functionality D.S. of from about 0.05 to about 0.5 (leaving an unreacted or unsubstituted hydroxyl D.S. of from about 0.05 to about 0.95), and to thereby provide a polymerizable organic solvent-soluble product which is insoluble in water and copolymerizable with vinyl monomers. The product is prepared by reacting a cellulose ester or ether derivative with a catalyst and the acrylamide reagent at a pH of from about 4.2 to about 4.5. The reaction is carried out at a temperature between 80°C and 120°C for from one-half to three hours, while removing the water of reaction.
