Patent

CA 2235041

The invention concerns powdery complexes comprising iodine and a crosslinked polymer based on N-vinyl compounds and obtained by the dry heating of iodine and a polymer obtained by polymerizing monovinyl compounds (monomers A), of which the vinyl group is bonded to an N-atom of a nitrogenous heterocyclic ring, in the presence of between 0.5 and 10 wt %, relative to the monomers (A), of a compound (B) of general formula (I), A standing for -CH- or an N-atom and n being 2 or 3. The complexes are suitable for producing anti-diarrhoeal agents.

Complexes en poudre formés d'iode et d'un polymère réticulé à base de composés N-vinyliques, obtenus par chauffage à sec de l'iode et d'un polymère, lui-même obtenu par polymérisation de composés monovinyliques (monomères A), dont le groupe vinyle est lié à un atome N d'un hétérocycle contenant de l'azote, en présence de 0,5 à 10 % en poids, par rapport aux monomères (A), d'un composé (B) de formule générale (I), dans laquelle A désigne un -CH- ou un atome N et n=2 ou 3. Ces complexes conviennent pour la fabrication d'antidiarrhéiques.
