Abstract: Ethyl acrylate and methyl acrylate have been graft-copolymerized onto wool fibre under nitrogen atmosphere using gamma rays as initiator. Relative mass increase of grafting (w_rig) has been determined as a function of total dose and monomer concentration. The effect of solvent composition and of H₂SO₄ as additive has been studied in air: too. It is interesting to note that grafting is higher when an optimum ratio w(H₂O):w(MeOH) is used as compared to that obtained in pure H₂O or MeOH as reaction medium.. Addition of H₂SO₄ promotes grafting. Grafting is higher in nitrogen atmosphere. A plausible mechanism to explain these results has been suggested.
