摘要：

Oxygen-organosolv lignins, isolated from spent liquors after delignification of wood in different acidic organic solvent-water media, were used as unmodified macromonomers in conjunction with an oligoethyleneoxide di-isocyanate. This led to crosslinked elastomeric polyurethanes which were thoroughly characterized. It was found that the nature of the organic solvent used for the organosolv pulping had an influence on the reactivity of the isolated lignins towards the di-isocyanate because of the variation in the amount of alcoholic groups caused by reactions with solvent molecules during the delignification.
