Synthese und Charakterisierung alternierender Polyesteramide auf Basis von Aminoalkoholen und cyclischen Anhydriden
The present thesis deals with the synthesis and the properties of alternating poly(ester amide)s based on a,w-amino alcohols and cyclic anhydrides. The synthesis of the poly(ester amide)s is performed by polycondensation of linear AB-monomers (a-carboxyl-w-hydroxy amides), in some cases …

Isocyanate-free synthesis of (functional) polyureas, polyurethanes, and urethane-containing copolymers
The subject of this dissertation is the preparation and characterization of (functional) polyureas, polyurethanes, and urethane-containing copolymers without using isocyanates or phosgene by step-growth reactions in bulk or solution. An important aspect of this thesis was the use of easily …

From cyclic carbonate bifunctional couplers to amphiphilic poly(ethylene imine)s
This dissertation is concerned with two subjects: bifunctional couplers and multifunctional poly(ethylene imine)s (Figure 1). Bifunctional couplers discussed in this thesis are mostly bearing at least one five-membered ring carbonate. These bifunctional couplers were suitable for the selective …
