Abstract (en)
[origin: DE10008880A1] Biodegradable polymer conjugates (I) for microencapsulating solid or dissolved substances in organic solvents or aqueous emulsions, and comprising an enzymatic cleavage site, are new. Biodegradable polymer conjugates (I) for microencapsulating solid or dissolved substances in organic solvents or aqueous emulsions, and comprising an enzymatic cleavage site, are new. R<1>n-P-(Q-P<2>)i-R<2>m (I) P<1>, P<2> = macromolecular structures; R<1>, R<2> = terminal groups, protecting groups, receptor molecules or labels; i, m, n = independently 0 or 1; and Q = an at least bifunctional structure with hydrophilic properties. An enzymatic cleavage site is present between the R and P substructures and/or within Q.
