| 摘要 |
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.
