  1. 6. 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.

  3. 7. Lipase selectivity in functional polyester synthesis

    Författare :Cecilia Hedfors; Karl Hult; Romas Kazlauskas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : Enzyme selectivity means that the enzyme´s preferences towards competing substrates will be different. In this thesis, the enzyme selectivity has been studied for utilization in synthesis of functionalized macromonomers. LÄS MER

  4. 8. Branched aliphatic polycarbonates : synthesis and coating applications

    Författare :Peter Löwenhielm; KTH; []
    Nyckelord :polymer technology;

    Sammanfattning : The overall aim of this thesis is to describe the synthesisof branched aliphatic polycarbonates and show the potentialapplication of these polymers in the field of powder coatings.The characterization of the polycarbonates was facilitated bythe study of a series of bis-MPAdendrimers, which served asreference of perfectly branched polymers.

  5. 9. Synthesis and characterization of dendritic architectures

    Författare :Andreas Nyström; Anders Hult; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Chemistry; Kemi;

    Sammanfattning : The goal of this work was to synthesize different dendritic architectures and evaluate the effect from the dendrons on the material properties. The work presented in this licentiate thesis, Synthesis and Characterization of Dendritic Architectures, is divided into major parts. LÄS MER

  7. 10. Amphiphilic Graft Copolymer Electrolytes for Lithium-Ion Polymer Batteries. - Preparation and Characterisation

    Författare :Patrik Gavelin; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; Kemiteknik och kemisk teknologi; Chemical technology and engineering; transport dynamics; ion conductivity; solid polymer electrolyte; gel electrolyte; macromonomer copolymerization; amphiphilic graft copolymer;

    Sammanfattning : In the present work amphiphilic graft copolymers were prepared by free radical copolymerization of macromonomers in solution. The graft copolymers consisted of methacrylate backbones bearing ethylene oxide (EO)n side chains of varying length as ionophilic groups, and fluorocarbon (CF2)6 side chains or hydrocarbon groups as ionophobic groups.
