This work describes the characterization and chemical modification by hydroxymethylation with F of two commercial lignosulfonates from different sources (hard and soft wood) and isolation processes (sulfite method and sulfonation of kraft lignin) in order to evaluate their potential use in the synthesis of PF resols.
