Abstract
(DE)
Gegenstand der Erfindung sind feuchtigkeitshärtbare Prepolymere (A), die über mindestens ein Strukturelement, ausgewählt aus den allgemeinen Formeln [1] bis [3], -NR2-B-SiL4 [1], =NR-B-SiL4 [2], [3], N-B-SiL4 verfügen, wobei L einen einzähligen Liganden, der ausgewählt wird aus Fluor-, Alkohol-, Carbonsäure- und Hydroximrest, L2 einen zweizähligen Liganden, der ausgewählt wird aus Diol-, Aminoalkohol-, Hydroxycarbonsäure-, Aminocarbonsäure- und Dicarbonsäurerest, mit der Massgabe, dass die vier Liganden L in der Lage sind, das pentakoordinierte Siliciumatom zu stabilisieren und B, und R die in Anspruch 1 bezeichneten Bedeutungen aufweisen, wobei das Stickstoffatom in der allgemeinen Formel [2] als endocyclisches Stickstoffatom Teil eines aliphatischen Heterozyklus ist, und das Stickstoffatom in der allgemeinen Formel [3] als endocyclisches Stickstoffatom Teil eines aromatischen Heterozyklus ist.
(EN)
The invention provides moisture-curable prepolymers (A) which have at least one structural element selected from the general formulae [1] to [3], -NR2-B-SiL4 [1], =NR-B-SiL4 [2], [3], N-B-SiL4 where L is a monodentate ligand which is selected from fluorine, alcohol, carboxylic acid and hydroxime radical, L2 is a bidentate ligand which is selected from diol, amino alcohol, hydroxycarboxylic acid, aminocarboxylic acid and dicarboxylic acid radical, with the proviso that the four ligands L are capable of stabilizing the pentacoordinated silicon atom and B, and R is as defined in claim 1, where the nitrogen atom in the general formula [2], as an endocyclic nitrogen atom, is part of an aliphatic heterocycle, and the nitrogen atom in the general formula [3], as an endocyclic nitrogen atom, is part of an aromatic heterocycle.
(FR)
L'invention concerne des prépolymères (A) durcissables à l'humidité, constitués d'au moins un élément structural, choisi parmi les formules générales [1] à [3], -NR2-B-SiL4 [1], =NR-B-SiL4 [2], [3], N-B-SiL4, L représentant un ligand monovalent choisi parmi les radicaux fluor, alcool, acide carboxylique, hydroxime, L2 représentant un ligand bivalent choisi parmi les radicaux diol, aminoalcool, acide hydroxycarboxylique, acide aminocarboxylique et acide dicarboxylique, à condition que les quatre ligands L soient en mesure de stabiliser l'atome de silicium pentacoordinant, B et R ayant les significations données dans la revendication 1. Selon l'invention, l'atome d'azote dans la formule générale [2] fait partie d'un hétérocycle aliphatique en tant qu'atome d'azote endocyclique et l'atome d'azote dans la formule générale [3] fait partie d'un hétérocycle aromatique en tant qu'atome d'azote endocyclique.
