Abstract
Process for the preparation of water-soluble basic resins containing nitrogen, characterized in that 2-amino-imidazoline compounds of general formula I are heated ** (See formula) ** wherein A means an organic radical linked to alpha, beta-carbon atoms with the two nitrogen atoms of the ring, optionally as salts, alone or together with high-boiling organic solution intermediates and, if necessary in presence of condensation means, at higher temperatures, preferably at more than 120º to about 280º, until approximately half a mole of ammonia is dissociated per mole of starting product and because the condensation products are still subjected to a subsequent condensation with reagents that form bridges.
