Abstract (en)
[origin: WO2019043054A1] The invention relates to a reactive adhesive containing the reaction product of a polyester - formed from the monomers A, B and C, wherein A = phthalic acid or phthalic anhydride, B = at least one organic acid with at least two acid groups or the corresponding anhydride or the corresponding ester, provided that B is not equal to A, and C = at least one diol, and wherein the molar ratio of the monomers A to the monomers B is 1:10 to 10:1 - as a polyol and optionally one or more further polyols with a diisocyanate, characterised in that the average OH value of the used polyols is 10 to 30 mg KOH/g of polyols, the ratio of OH of the used polyols to NCO groups of the used diisocyanates is between 1-1.2 and 1-4.0, and the reaction product has a viscosity of 1 to 200 Pa·s at 130°C. The invention also relates to a method for the production thereof, and to the use of the reactive adhesive.
