    Abstract: Aqueous dispersions containing a polyurethane essentially built up from a) organic polyisocyanates and optionally secondary amounts of monoisocyanates, b) dihydroxyl compounds having a molecular weight of from above 500 to 10000 g/mol and containing at least 2 carboxyl or carboxylate groups in the molecule, which are obtainable by reacting dihydroxyl compounds with tetracarboxylic dianhydrides in a molar ratio of from 2:1 to 1.05:1, c) optionally polyhydroxyl compounds having a molecular weight of from above 500 to 5000 g/mol, other than (b), d) optionally compounds containing at least one group which is reactive towards isocyanates and at least one group which is anionic or can be converted into an anionic group, having a molecular weight of from 60 to 500 g/mol, e) optionally, compounds other than d) and e) containing at least 2 groups which are reactive towards isocyanates, having a molecular weight of from 60 to 500 g/mol. l

    Abstract: Light-weight building panels based on mineral fibres A and thermoplastic binders contain 1 to 25% by weight, relative to A, of a copolymer B having a glass transition temperature from 70 to 105 DEG C and built up essentially from 50 to 98% by weight of methyl methacrylate I, 2 to 50% by weight of one or more acrylates II of C1-C8-alkanols and 0 to 2.5% by weight of one or more crosslinking monomers III as binders, 0 to 150% by weight of fillers C and, relative to B, 0.2 to 15% by weight of one or more amines F of the general formula in which R is C8-C18-alkyl or C8-C18-alkenyl, U and V are C2-C4-alkylene, X and Y are hydrogen, C1-C18-alkyl or C2-C18-alkenyl and n and m are integers from 0 to 10, or acid addition salts thereof.
