FIELD: chemistry.
SUBSTANCE: invention relates to blocked polyisocyanates, applied for obtaining of bonding means for thermohardening lacquers, paints and such other subjected to thermo processing systems, as adhesive substances or elastomers, they serve as means for net-like structure formation for polyol components. Blocked polyisocyanates have general formula (I): 
Said polyisocyanates are obtained by interaction of polyisocyanates of general formula (II)
with secondary amines of general formula (III) 
EFFECT: obtaining of polyisocyanates, which ensure lower temperature of net-like structure formation and, therefore thermoprocessing, they are also stable as to crystallisation in organic solutions, which favours appreciable reduction of viscosity of such solutions, because it allows to reduce solvent content.
