    摘要: 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.

    摘要: The invention relates to a silylated polyurethane that is manufactured by reacting at least one polyether compound having an OH number per DIN 53783 between 3 and 20 mg KOH/g, made up of at least two polyoxyalkylene blocks A and B, the number of carbon atoms in the alkylene units of blocks A and B differing by at least 1, with one or more isocyanatosilanes of formula (I): OCN—R—Si—(R1)m(—OR2)3-m, in which m is 0, 1, or 2, each R2 is an alkyl residue having 1 to 4 carbon atoms, each R1 is an alkyl residue having 1 to 4 carbon atoms, and R is a difunctional organic group, in order to cap the hydroxyl groups of the prepolymer with the isocyanatosilane, thereby forming a silylated polyurethane that comprises alkoxysilyl groups as reactive end groups. The silylated polyurethanes that are described are suitable for the manufacture of adhesive, sealant, or coating-agent preparations having good mechanical properties.
