Graft copolymerization of methyl methacrylate onto Asplund pulp (AKAMATSU, Pinus densiflora) was investigated and the following results were obtained ; (1) H_2O_2-Fe^<2+> initiation system was very effective for the grafting. (2) Alcohol-benzene extraction of Asplund pulp gave no effects on the total conversion ratio of MMA in the concentration range of H_2O_2 more than 1.8x10^<-2> mole/liter. (3) Asplund pulp itself was found to accelerate the rate of polymerization of MMA. (4) The weight of PMMA branches grafted onto carbohydrate moieties was much more than the weight of the branches onto lignin, remarkably in the early stage of graft copolymerization.
