    • The invention relates to a method for producing cross-linkable formulations. In a first step of the method, at least one α,ω-difunctional organic polymer of formula (1) X-A-X (1) is converted into organyloxysilyl-terminated polymers P1, using organofunctional silanes of formula (2) Y—R—Si—(R1)m(—OR2)3m (2), in the presence of catalysts (A) selected from the group consisting of potassium, iron, indium, zinc, bismuth and copper compounds. In said formulae, R is a bivalent, optionally substituted hydrocarbon group which comprises between 1 and 12 carbon atoms and can be interrupted with heteroatoms, R1 and R2 are the same or different, monovalent, optionally substituted hydrocarbon groups which comprise between 1 and 12 carbon atoms and can be interrupted with heteroatoms, A is bivalent, optionally substituted hydrocarbon group which comprises at least 6 carbon atoms and can be interrupted with heteroatoms, m is equal to 0, 1 or 2, X is a hydroxyl group and Y is an isocyanate group, or X is an isocyanate group and Y is a hydroxyl group or a primary or secondary amino group. In a second step, the polymers P1 obtained in the first step are mixed with a silane condensation catalyst (B) selected from the group consisting of compounds of elements of the third main group and/or fourth secondary group and heterocyclic organic amines, amine complexes of the element compounds, or the mixtures thereof. Optionally, said mixture is mixed with other substances (C). The formulations do not contain organic tin compounds, and are suitable for using as adhesives, sealants, or coating agents.

    • Silylated polyurethanes can be manufactured by reacting at least one polyol compound, having a molecular weight from 4000 to 20,000 dalton, with a diisocyanate, with a stoichiometric excess of the diisocyanate compound with respect to the polyol compound or compounds, with the result that a polyurethane prepolymer that is isocyanate-terminated is formed; and by subsequently reacting the polyurethane prepolymer with one or more OH-terminated silanes of formula (1) to yield a polyurethane having predominantly terminal alkoxysilyl groups. In formula (1), m is equal to 0, 1, or 2, R1 is an alkyl residue having 1 to 4 carbon atoms, R2 is an alkyl residue having 1 to 4 carbon atoms, R3 is a divalent organic residue having 1 to 12 atoms, selected from C, N, S, and/or O, in the chain, but by preference exclusively carbon atoms, R4 is a hydrogen atom or an alkyl residue having 1 to 10 carbon atoms, and R is a difunctional organic group, preferably a linear or branched alkyl group having 1 to 6 carbon atoms. The silylated polyurethanes are suitable for use in a preparation as an adhesive, sealant, or coating agent.
