| 摘要 |
The invention relates to a curable composition, which comprises: a) at least one polymer having at least one silicon-containing group of the formula -Si(R1)k(Y)3-k, as defined herein, b) at least one titanium compound of the formula Ti(L)n(NX2)m or Ti(R3)(L)3, wherein each X independently stands for a hydrogen atom, a hydrocarbon group having 1 to 20 C atoms, which can optionally contain one or more heteroatoms, in particular nitrogen atoms, or a silicon-containing organic group or two X's form a heterocyclic ring together with the nitrogen atom to which said X's are bonded; each L independently stands for a hydrolyzable oxygen- or nitrogen-containing organic group, in particular an alkoxy group; R3 stands for a hydrocarbon group having 1 to 20 C atoms, which can optionally contain one or more heteroatoms, in particular silicon atoms; and m is 1, 2, 3, or 4 and n is 0, 1, 2, or 3, wherein m + n = 4; and c) optionally at least one compound that has a hydrolyzable silicon-containing group and a molecular weight in the range of 100 to 1000 g/mol, preparations that contain said compositions, and use thereof. |
