22236-569 ABSTRACT Polymers from ethylenically unsaturated monomers, cross-linked by a substituted or unsubstituted divinylazobenzene are useful as carriers or capusles for medicaments, which are degraded by the enzymes of the upper gastrointestinal tract or which must be trasferred intact past the upper gastrointestinal tract, to deliver the medicament to the large intestine. Polymers containing monomeric units of the formula H2C=CH-C6H4-N=N-M, wherein M is the residue of an amino-containing medicament, are useful as carriers for therapeutic agents or as therapeutic agents per se.
