1. Hyperbranched aliphatic polymers : synthesis and characterization of hyperbranched structure
Sammanfattning : .... LÄS MER
2. Diffusion, Swelling and Mechanical Properties of Polymers
Sammanfattning : Polymers capability to withstand harmful interactions withdifferent environments can be determined by looking at thetransport and mechanical properties of the material exposed tothe medium. The diffusion of a penetrant in a polymer and itsswelling characteristics can be verified by a simplesorption-desorption experiment followed by methodical analysisof the data. LÄS MER
3. Polymer Nanocomposites in Thin Film Applications
Sammanfattning : The introduction of a nanoscopic reinforcing phase to a polymer matrix offers great possibilities of obtaining improved properties, enabling applications outside the boundaries of traditional composites. The majority of the work in this thesis has been devoted to polymer/clay nanocomposites in coating applications, using the hydroxyl-functional hyperbranched polyester Boltorn® as matrix and montmorillonite clay as nanofiller.

4. Exploring bis-MPA Based Dendritic Structures in Biomedicine
Sammanfattning : In the last decades there has been significant advances in polymer chemistry. New coupling chemistries, polymerization techniques and accelerated approaches enable researches to push the limits of structural control. LÄS MER
5. Foam, Fire and Free Volume - Chemical and Physical Aspects of Porous Polymers
Sammanfattning : Automotive seating has been under continous development since it was described for the first time in 1885. At that time one could read about a “padded leather bench seat sitting on springs mounted directly to the frame of a horse-less carriage”. LÄS MER
