Abstract
The invention relates to a curable composition comprising a) at least one polymer having at least one terminal group of the general formula (I)-A-R—SiXYZ  (I),wherein A is a divalent or trivalent bonding group containing at least one heteroatom, R is selected from divalent hydrocarbon residues having 1 to 12 carbon atoms, X, Y, Z are, independently of one another, selected from the group consisting of a hydroxyl group and Cto Calkyl, Cto Calkoxy, Cto Cacyloxy groups and —CH—N—R' wherein N is oxygen, nitrogen or sulfur, preferably oxygen, and R′ is selected from Cto Calkyl groups, preferably a methyl group, wherein X, Y, Z are substituents directly bound with the Si atom or the two of the substituents X, Y, Z form a ring together with the Si atom to which they are bound, and at least one of the substituents X, Y, Z is selected from the group consisting of a hydroxyl group, Cto Calkoxy or Cto Cacyloxy groups, and n is 0 or 1; and b) at least one compound of the general formula (II) wherein Ris same or different and is, independently from one another, selected from the group consisting of a hydrogen atom and hydrocarbon residues having 1 to 12 carbon atoms, Ris same or different and is, independently from one another, selected from hydrocarbon residues having 1 to 12 carbon atoms, Ar is selected from aryl groups, and n is an integer selected from 3 to 9; and adhesive, sealant, or coating materials comprising the composition and use thereof.
