Beschreibung
Zusammenfassung:	Immobilized biologically active material in particle form is prepared by cross-linking with glutaraldehyde and polyazetidine. An aqueous dispersion or solution of biologically active material is partially cross-linked with glutaraldehyde, a wet pasty mass is recovered by dewatering and the mass is sub-divided into discrete particles. A polyazetidine prepolymer is added before, at the beginning or subsequent to partially cross-linking but prior to subdividing the pasty mass into particles, and the prepolymer is allowed to cross-link.
