57 Zusammenfassung AB [DE] Die Erfindung beschreibt die Herstellung von thiol-funktionalisierten copolymeren Polyestern durch lipase-katalysierte Veresterung und Umesterung von bifunktionellen Alkandicarbonsäuren oder deren Estern mit polyfunktionellen Mercaptoalkanolen, wobei die Reaktionspartner ohne Lösungsmittel in Gegenwart von Lipasen reagieren und die dabei gebildeten niedermolekularen flüchtigen Nebenprodukte im Vakuum entfernt werden. Thiol-funktionalisierte copolymere Polyester können als optische Werkstoffe sowie wegen ihrer antioxidativen und bioziden Eigenschaften als Coatings, Additive für Schmiermittel, Zusätze zu Körperpflegemitteln und migrationsbeständige Komponenten von Polymergemischen eingesetzt werden. $F1
