SOLUTIONS OF POLYCONDENSATES WHICH HAVE HETEROCYCLIC RING SYSTEMS CONTAINING N AS STRUCTURAL UNITS, WITH IMPROVED LIABILITY ON INORGANIC SUBSTRATES

摘要

Solutions of polycondensates which have N-containing heterocyclic ring systems as structural units, or solutions of intermediates of these polycondensates, in inorganic solvents, contain from 0.1 to 20% by weight, based on the polycondensates or the intermediates thereof, of one or more azidosilanes of the general formula N3-R3-Si-R1n(OR2)3-nI where R1 is C1-C3-alkyl, phenyl, benzyl or toluyl, R2 is C1-C4-alkyl, C2-C4-alkoxyalkyl, phenyl or benzyl, R3is C1-C8-alkylene which may be interrupted by an oxygen atom, a sulfur atom or a -(N-R4) -group, where R4 is hydrogen, methyl, ethyl or phenyl, and n is 0, 1 or 2.
