The present invention relates to composite elements comprising (i) plastic, adhering to which there is (ii) a polyisocyanate polyaddition product, where the polyisocyanate polyaddition product is obtained via mixing of (a) isocyanate with (b) compounds having groups reactive toward isocyanates, (c) catalysts and optionally additional products to give a reaction mixture and converting the reaction mixture to a polyisocyanate polyaddition product, where the compounds (b) comprise a polyester polyalcohol as adhesion promoter, capable of production via polycondensation of an acid component and one or more low-molecular-weight diols whose molar mass is less than 500 g/mol, in excess, where the acid component comprises from 83 to 97 mol % of adipic acid and from 3 to 17 mol % of phthalic acid, isophthalic acid, and/or terephthalic acid. The present invention also relates to components in the fitting-out or aircraft, of vehicles, or of buildings, and to insulation comprising this type of composite element.

Adhesion promoter for adhesive composites composed of plastic and of a polyisocyanate polyaddition product

The invention provides a process for preparing polyester polyols of polyhydric alcohols by mono- or polyesterification of at least one carboxylic acid having at least two acid groups and/or at least one derivative of a dicarboxylic acid with polyhydric alcohols, optionally with the addition of a catalyst, while removing the water of reaction, wherein the polyhydric alcohol used has a formaldehyde acetal content of less than 500 ppm.

Method for producing polyesterpolyols of polyvalent alcohols

Polyester-polyether block copolymers can be prepared by catalytic addition of alkylene oxides onto H-functional initiator substances, using polyester alcohols as H-functional initiator substances and multimetal cyanide compounds as catalysts.
