    Abstract: Polyester polyol is prepared by polycondensation of an alcohol/ester mixture with a carboxylic acid mixture and polyalkylene terephthalate. Polyester polyols (I) based on alcohols and carboxylic acids and/or carboxylic acid derivatives as well as polyalkylene terephthalate are prepared by polycondensation of a raw material mixture containing (A) a mixture of one or more alcohols having at least 2 hydroxyl groups and 10-30 wt.% of a linear and/or cyclic ester compound, (B) a mixture of 10-33 wt.% succinic acid, 39-50 wt.% glutaric acid and 16-45 wt.% adipic acid and (C) polyalkylene terephthalate whereby the wt. ratio of (A):(B):(C) is 35-60:10-25:20-55.

    Abstract: Polyol mixture containing: (i) a polyester-ol obtained from an olefin-unsaturated carboxylic acid copolymer and a mono-alcohol, a 2-9C polyhydroxy compound (VII) or a more than 10C diol (II), or from diol (II), compound (VII) or a poly-carboxylic acid; or (ii) a polyether-ol from diol (II) or an alkylamine and an alkylene oxide. A polyol mixture containing: (A) 0.1-100 wt.% polyester-ol (i) or polyether-ol (ii) with 10-10000 carbon atoms, or at least two of these (not derived from castor oil or dimer fatty acid), in which (i) is obtained from (a) a copolymer (I) of an olefin (IV) with an alpha , beta -unsaturated carboxylic acid (V) and a mono-alcohol (VI) or a 2-9C polyhydroxy compound (VIII) or a diol (II) with 10 or more carbon atoms, or a mixture of two or more of these, or from (b) diol (II) and polyhydroxy compound (VII) or a carboxylic acid (VIII) with at least two COOH groups, or a mixture of two or more of these, and (ii) is obtained from (c) diol (II) and an alkylene oxide (IX) or from (d) an alkylamine (III) and alkylene oxide (IX); (B) 0-99.9 wt.% other polyester-ol(s) or polyether-ol(s); and (C) 0-10 wt.% additives. Independent claims are also included for: (1) a method for the production of polyurethanes by reacting a component containing this polyol mixture or alkylamine (III) with a polyisocyanate component; (2) polyurethanes obtained by this method; (3) polyurethanes containing a polyol mixture as described; (4) formed objects containing polyol mixtures or polyurethanes as described.
