   Författare :Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

   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

4. 8. Dendrimers : Synthesis, Characterization and Use in Thiol-Ene Networks

   Författare :Camilla Nilsson; Eva Malmström; Andreas Heise; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer; molecular physics; Polymer chemistry; Polymerkemi;

   Sammanfattning :  Dendrimers are perfectly branched, well-defined macromolecules with a layered structure and a large amount of peripheral end groups. The high functionality in combination with the possibility of dendrimers to adopt a globular shape at high molecular weights, gives them very unique properties. LÄS MER

5. 9. Porous polymeric materials for chromatography : Synthesis, functionalization and characterization

   Författare :Emil Byström; Knut Irgum; Camilla Viklund; Solomon Tesfalidet; Klaus K Unger; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; porous polymer monolith; pore size distribution; nitrogen sorptiometry; mercury intrusion porosimetry; scanning and transmission electron microscopy; plasma functionalization; Analytical chemistry; Analytisk kemi; Separation methods; Separationsmetoder; Polymer chemistry; Polymerkemi; analytisk kemi; Analytical Chemistry;

   Sammanfattning : Background: Separation science is heavily reliant on materials to fulfill ever more complicated demands raised by other areas of science, notably the rapidly expanding molecular biosciences and environmental monitoring. The key to successful separations lies in a combination of physical properties and surface chemistry of stationary phases used in liquid chromatographic separation, and this thesis address both aspects of novel separation materials.
