Pressurized, blowing-agent-containing isocyanate semiprepolymer mixtures based on mixtures of polyhydroxyl compounds and monoalcohols and/or hydroxyketones, the use thereof for the production of polyurethane foams, and a process therefor |
摘要 |
The invention relates to pressurized, blowing-agent-containing isocyanate semiprepolymer mixtures, advantageously having an isocyanate content of from 5 to 25% by weight, based on organic polyisocyanates and polyhydroxyl compounds which are used in combination with a linear, branched or cyclic, saturated or olefinically unsaturated monoalcohol having 1 to 25 carbon atoms and/or hydroxyketones, preferably beta -hydroxyketones, the use thereof for the production of one-component polyurethane foams by allowing the isocyanate semiprepolymer mixtures to depressurize, and a process therefor.
