FIELD: chemistry.

SUBSTANCE: invention relates to aldimines used to produce a polymer precursor, obtained via reaction of at least one sterically hindered aliphatic aldehyde A of formula with an aliphatic amine B, where all values of substitutes are given in the claim, via a condensation reaction with splitting of water, a product containing an aldimine-containing compound, and use thereof as a protected cross-linking agent for the polymer precursor and as a source of amines [H₂N]_m-R⁴-[XH]_y (B).

EFFECT: obtaining polymer precursors containing isocyanate groups, which are characterised by high stability during storage.
