The feasibility of using lignosulfonate (LS) from acid sulphite pulping of eucalyptus wood as an unmodified polyol in the formulation of polyurethane (PU) adhesives was evaluated. Purified LS was dissolved in water to simulate its concentration in sulphite spent liquor and then reacted with 4,4'-diphenylmethane diisocyanate (pMDI) in the presence or absence of poly(ethylene glycol) with <i>M</i><sub>w</sub> 200 (PEG<sub>200</sub>) as soft crosslinking segment. The ensuing LS-based PU adhesives w ...[more]
