The radiation-induced graft copolymerization of styrene and various kraft softwood lignins was studied. Expression of the results as the usual "per cent graft" was impossible, because grafting caused the lignin to become extractable in solvents for the styrene homopolymer. However, evaluation of the

## Abstract The effect of addition of lignin model compounds on the polymerization rate and molecular weight of polymer in the radiationβinduced polymerization of styrene was studied. Guaiacol, a model for softwood lignin, reacted slowly with styrene radicals, while 2,6βdimethoxyphenol, a hardwood
Cross-linked copolyesters containing kraft iignin were synthesized with sebacoyl chloride and terephthaloyl chloride by bulk polymerization. Polyethylene glycol was used as co-monomer and solvent for lignin. The effects of COC1/OH ratio, percentage of kraft lignin and molecular weight of PEG on the
