Patent ID: 8076444

Claim:
A curable composition encompassing a) a polymer P with at least two end groups of the following formulae (I) and (II) -A m -K 1 —SiXYZ (I), -A m -K 2 —SiXYZ (II), and one or both of polymers P 1 and P 2 , wherein the polymer P 1 has end groups of the following formula (I) -A m -K 1 —SiXYZ (I), and the polymer P 2 has end groups of the following formula (II) -A m -K 2 —SiXYZ (II), wherein A signifies a divalent binding group, K 1 , K 2 independently of one another denote a divalent aliphatic hydrocarbon group which has a main chain of 1 to 6 carbon atoms, wherein the hydrocarbon groups K 1 , K 2 are different, X, Y, Z independently of one another denote a hydroxy group or a hydrolyzable group, and m assumes the values 0 or 1.
