ABSTRACT:
The invention relates to silane cross-linking curable compositions, comprising a polymer P with at least two terminal groups of the following formulae (I) and (II) -Am-K1—SiXYZ (I), -Am-K2—SiXYZ (II), and/or two polymers P1and P2, the polymer P1having terminal groups of the following formula (I) -Am-K1—SiXYZ (I), and the polymer P2having terminal groups of the following formula (II) -Am-K2—SiXYZ (II). In said formulae, A represents a bivalent binding group K1and K2independently of one another represent a bivalent aliphatic hydrocarbon group with a main chain of between 1 and 6 carbon atoms, the hydrocarbon groups K1, K2being different, X, Y and Z independently of one another represent a hydroxy group of a hydrolysable group and m stands for 0 or 1.
