1. Synthesis and characterization of dendritic macromolecules based on 2,2-bis(hydroxymethyl)propionic acid
Sammanfattning : Dendrimers are a relatively new type of macromolecules characterized by a well-defined, highly branthed, layered structure with a multitude of chain ends, adopting a globular shape at higher molar masses. Dendrimers are usually constructed from ABx type of monomers in either one of the two step-wise approaches known as thedivergentor theconvergent growth approach. LÄS MER
2. Dendrimers and dendronized polymers : synthesis and characterization
Sammanfattning : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. LÄS MER
3. Microbial and enzymatic syntheses of polymer building blocks through selective transformations of polyols and furans
Sammanfattning : AbstractTransition from fossil- to bio-based economy is a critical step towards reduction of greenhouse gas emissions and climate change, and hence for achievement of sustainable communities and environment. In order to be fossil-free, the chemical and material industry is in need of carbon-neutral building blocks from renewable resources for the diverse array of products that are currently produced from olefins and aromatics.

4. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques
Sammanfattning : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. LÄS MER
5. Synthesis of Carbohydrate Mimics and Development of a Carbohydrate Epimerisation Method
Sammanfattning : In this thesis the synthesis of several hydrolytically stable carbohydrate mimics with the potential to function as glycosidase or lectin inhibitors are described. This work is presented in Chapters 2-5. LÄS MER
