Patent ID: 8372514

Claim:
A moisture-curing composition comprising: at least one polymer SP1 having formula (IV) at least one polymer SP2 having formula (V) and optionally at least one polymer SP3 with end groups of formula (III) not including urea groups or urethane groups, where: X 2′ stands for wherein R 4 stands for methyl, ethyl, propyl, or butyl; X 3 stands for O or NH or NR 5′ , where R 5′ stands for a linear or branched hydrocarbon residue with 1 to 20 C atoms; R 1 and R 3 each independently stand for an alkyl group with 1 to 10 C atoms; R 2 stands for an alkyl group with 1 to 5 C atoms; R 5 stands for a hydrogen atom; Y 3 stands for a hydrolyzable residue; Q stands for a linear or branched alkylene residue with 3 to 6 C atoms; A 1 stands for a divalent residue of a polymeric diol or polymeric diamine after removal of hydroxyl groups or amino groups; A 2 stands for a divalent residue of an isocyanate-group containing polymer after removal of isocyanate groups; and a stands for 0 or 1; and the dashed lines each represent binding of a group to the polymer, with the proviso that: the weight ratio of polymer SP1 to polymer SP2 is a value between 0.1 and 0.8, and if polymers SP2 and SP3 are simultaneously present in the composition, the weight ratio of polymer SP2 to polymer SP3 has a value >1.1.
