Patent ID: 8399102

Claim:
A moisture-curing composition comprising a) at least one silane-functional polyurethane polymer P having end groups of the formula (I) where R 1 is an alkyl group having 1 to 8 C atoms; R 2 is an acyl group or alkyl group having 1 to 5 C atoms; R 3 is a linear or branched, optionally cyclic, alkylene group having 2 to 12 C atoms, optionally with aromatic fractions, and optionally with one or more heteroatoms; a is 0, 1 or 2; and b) at least one reaction product R, prepared from at least one aminosilane A1 of the formula (IX) with n =1 or 2 and b =0 or 1, R 13 being an alkyl group having 1 to 8 C atoms, and R 14 =methyl or ethyl or isopropyl, and at least one silane-group-free alkene M of the formula (II) or (III) or (IV) where R 9 is R 12 or —CN, and R 10 is a substituent selected from the group consisting of —COOR 12 , —CONHR 12 , —CON(R 12 ) 2 , —CN, —NO 2 , —PO(OR 12 ) 2 , —SO 2 ,R 12 , and —SO 2 OR 12 , R 11 is a substituent selected from the group consisting of —R 12 , —COOR 12 , —CH 2 —COOR 12 , and —CN, and R 12 is a hydrogen atom or a monovalent, optionally heteroatom-containing, hydrocarbon radical having 1 to 20 C atoms.
