Abstract RU 2544238 C2

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining cyclic guanidine, which can be applied in coating compositions, in particular in electrically precipitated coating compositions. Method includes reaction of (i) cyanamide, (ii) polyamine and (iii) weak acid with 5.0<pKa<13.5. Invention also relates to method of obtaining polymer resin and method of obtaining cyclic guanidine, containing 6-membered ring.

EFFECT: claimed method makes it possible to reduce amount of wastes in production of cyclic guanidines.
