摘要： The invention relates to prepolymers which contain isocyanate groups and which can be produced by reacting an isocyanate mixture, said mixture being predominantly comprised of diphenylmethane diisocyanates and polyphenyl polymethylene polyisocyanates, with a maximum proportion of two-core isomers of 74 wt.% with at least 4 functional polyols or with a mixture of polyols having an average functionality of at least 4. The polyols or polyol mixture comprise(s) a hydroxyl value ranging from 200 to 1650 mg KOH/g and an average molar mass of less than 1100 g/mol with an NCO content of at least 30.0 wt.%. In addition, the invention relates to a method for producing these prepolymers which contain isocyanate groups, to their use for producing polyurethanes, and to a method for producing polyurethanes by reacting at least one of the inventive prepolymers which contain isocyanate groups, optionally mixed with additional organic and/or modified organic isocyanates (a), with compounds having at least two reactive hydrogen atoms (b) in the presence of optional expanding agents (c), catalysts (d), optional additional auxiliary agents and/or additives (e).

摘要： Flame-resistant rigid foams based on isocyanate Flame-resistant rigid foams based on isocyanate are produced by reacting a) organic and/or modified organic polyisocyanates with b) at least one compound containing hydrogen atoms reactive toward isocyanates and, if desired, c) low molecular weight chain extenders and/or crosslinkers in the presence of d) blowing agents, e) catalysts f) at least one bromine-containing flame retardant and, if desired, g) further auxiliaries and/or additives, wherein predominantly tribromoneopentyl alcohol is used at bromine-containing flame retardant and the crosslinking index of all compounds containing hydrogen atoms reactive toward isocyanates, including the bromine-containing flame retardant, is at least 3.0. The rigid foams based on isocyanate and produced by this process can be used as insulation materials.
