    摘要: 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, (d) if appropriate, blowing agent, and (e) if appropriate, further additives, to give a reaction mixture and permitting the reaction mixture to complete its reaction to give the polyisocyanate polyaddition product, where the compounds (b) having groups reactive toward isocyanates comprise a polyester polyalcohol as adhesion promoter, capable of production via polycondensation of an acid component and of 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 further 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, (d) if appropriate, blowing agent, and (e) if appropriate, further additives to give a reaction mixture and permitting the reaction mixture to complete its reaction to give the polyisocyanate polyaddition product, where the compounds (b) having groups reactive toward isocyanates comprise a polyester polyalcohol as adhesion promoter, capable of production via polycondensation of an acid component and of one or more low-molecular-weight diols whose molar mass is less than 500 g/mol, in excess, where the low-molecular-weight diols comprise from 5 to 66 mol % of 1,3-propanediol, based on the total amount of the diol. The present invention also relates to a process for the production of these composite elements, and to components in the fitting-out of aircraft, of vehicles, or of buildings, and to insulation comprising this type of composite element.
