title: Hydrophilic-hydrophobic biodegradable polymers: release characteristics of hydrogen-bonded, ring-containing polymer matrices.
abstract: Biodegradable hydrogen-bonded, ring-containing polymers were prepared. These included poly(enolketones) by the controlled oxidation of poly(vinyl alcohol), and poly(amide-amines) and poly(amide-enamine-esters) by the reaction of diketene with diamines. These polymers had both hydrophilic and hydrophobic properties and are potentially matrix materials for the controlled release of drugs.
