    摘要： The present invention relates to the use of compositions based on special isocyanate-terminated prepolymers as wood adhesives. The composition comprises at least one isocyanate-terminated prepolymer obtained by reacting at least one organic polyisocyanate and a mixture of at least two organic polyhydroxyl compounds containing at least 20 wt. % of fatty acid triglycerides containing hydroxyl groups, and at least 20 wt. % of polyethers having an average of at least two hydroxyl groups, and optionally auxiliary substances and additives.

    摘要： The present invention is directed to a process for the preparation of foam-containing polyurethane (urea) masses comprising reacting an isocyanate prepolymer containing cation groups with water in the presence of fillers. The isocyanate prepolymer is prepared by first i) reacting a polyisocyanate with a first polyol which contains partly or completely quaternized tertiary nitrogen, said polyol being prepared by reacting a tertiary amine containing compound with from 3 to 8 moles of propylene oxide per mol of nitrogen to thereby form a semi-isocyanate prepolymer and then ii) reacting said semi-isocyanate prepolymer with a second polyol different from said first polyol, to form said isocyanate prepolymer.
