Abstract
Compositions that can be cross-linked by a condensation reaction comprise an organic polymer having at least one organyloxysilyl radical (A) and compounds (B) of the formula (I) [R4P+]sX5−, wherein X is a group of the formula (II) O═PR1n(O−)m(OR2)3-n-m, and/or the condensates thereof having one or more P—O—P bonds or a group of the formula (III) −OC(═O)R1′.

A composition which is crosslinkable by a condensation reaction, comprising an organic polymer with at least one organyloxysilyl radical (A) and
- at least one compound (B) of the formula
- [R4P+]sXs− (I)
- in which
- s is 1, 2 or 3,
- R are identical or different and are optionally substituted hydrocarbon radicals with from 1 to 40 carbon atoms,
- X is a group of the formula
- O═PR1n(O−)m(OR2)3-n-m (I)
- and/or the condensates thereof with one or more P—O—P bonds, or a group of the formula
- −OC(═O)R1′ (III)
- in which
- R1 are identical or different and are optionally substituted hydrocarbon radicals optionally interrupted by oxygen atoms,
- R1′ are identical or different and are optionally substituted hydrocarbon radicals optionally interrupted by oxygen atoms,
- n is 0, 1 or 2,
- m is 1, 2 or 3 and
- m+n is 1, 2 or 3, and
