摘要: Polymers from ethylenically unsaturated monomers, cross-linked by a substituted or unsubstituted divinylazobenzene are useful as carriers capsules for medicaments, which degraded the enzymes of upper gastrointestinal tract must be transferred intact past tract, to deliver medicament large intestine. containing monomeric units formula H.sub.2 C═CH--C.sub.6 H.sub.4 --N═N--M, wherein M is residue an amino-containing medicament, therapeutic agents per se.
