| titleOfInvention |
Prepolymers containing isocyanate groups and process for their preparation |
| abstract |
The invention relates to prepolymers containing isocyanate groups, which can be prepared by reacting an isocyanate mixture consisting predominantly of diphenylmethane diisocyanates and polyphenylpolymethylpolyisocyanates with a proportion of binuclear isomers of at most 74% by weight with at least 4-functional polyols or a mixture of polyols with an average functionality of at least 4, where the polyols or polyol mixtures have a hydroxyl number of 200 to 1650 mg KOH / g and a number average molecular weight of less than 1100 g / mol, with an NCO content of at least 30.0% by weight. DOLLAR A objects of the invention are also a process for the preparation of these prepolymers containing isocyanate groups, their use for the preparation of polyurethanes and a process for the preparation of polyurethanes by reacting at least one prepolymer containing isocyanate groups according to the invention, optionally in a mixture with further organic and / or modified organic isocyanates ( a) with compounds having at least two reactive hydrogen atoms (b) in the presence of optionally blowing agents (c), catalysts (d) and optionally further auxiliaries and / or additives (e). |
