    Author : Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Nonlinear rheological characterization of cellulose nanocrystals based systems

    Author : Sylwia Wojno; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cellulose; rheo-PLI; CNC; FT-rheology; rheology;

    Abstract : In this thesis, cellulose nanocrystals based systems were investigated using advanced rheological characterization techniques, with a particular focus on nonlinear material response functions and Rheo-PLI (Polarized Light Imaging). Cellulose nanocrystals (CNCs) show enormous potential for many applications, either as material on its own or as renewable reinforcement in polymers. READ MORE

    Abstract : Polymer-based materials are widely used in the automotive industry for producing vehicle parts, for instance car bumpers, dash boards etc. A common manufacturing process for such components is injection moulding. READ MORE

  6. 4. Manufacturing and Characterization of Filled Polymeric Systems

    Author : Henrik Oxfall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PS; hybrid composites; EBA; computer simulations; graphene; rheology; mould filling; graphite nanoplatelets; powder injection moulding; electrical conductivity; elongational flow; thermal properties; jetting;

    Abstract : The physical properties are changed if fillers are added to a polymeric material. In this work a highly filled model system for power injection moulding (PIM) and graphite nanoplatelet (GNP) based nanocomposites have been manufactured and characterized. READ MORE

  7. 5. Dendrimers : Synthesis, Characterization and Use in Thiol-Ene Networks

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

    Abstract :  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. READ MORE
