The anionic graft polymerization of AN and MAN on cellulose acetate alkoxide derivative (Li, Na, K) was investigated in THF, DMF, and DMSO. Although the yield of the polymerization was high the extent of grafting of acrylonitrile was low (1.4–5.3% in DMF and DMSO and 20% in THF) due to homopolymerization caused by chain transfer to monomer. With methacrylonitrile which has no acidic α‐hydrogen the amount of grafted monomer was higher (37–72%).
