Graft copolymerization of methyl methacrylate on stone ground wood (SGW) of masson pine was investigated. The effect of lignin on grafting was carefully examined The phenolic hydroxyl groups of lignin were found to accelerate the decomposition of hydrogen peroxide and graft copolymerization of lignocellulose when minor ferrous ions were added to the system. Nevertheless, the α‐hydroxyl groups of lignin had no great influence on grafting. Also, the graft copolymerization could be initiated with low ferrous ions to the hydrogen peroxide molar ratio, and, additionally, the lignin was observed to be more suitable for grafting than was the hollocellulose.
