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

2. Design of renewable and functional polyamides and polyhydroxyurethanes with tunable structure-property relationships
Sammanfattning : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

3. Poly(ethylene-graft-ethylene oxide) Preparation and Properties in Polymer Blends
Sammanfattning : This thesis describes the preparation, characterisation and properties of poly(ethylene-graft-ethylene oxide) (PE-PEO). The grafting reaction was carried out with the grafting onto method using the carboxylic acid groups of poly(ethylene-co-acrylic acid) (PEAA) as reactive sites in an esterification reaction with poly(ethylene oxide) mono-methyl ethers (MPEO) of varying molecular weights: 750, 2000 and 5000.

4. Effects of a Novel Amphiphilic Graft Copolymer on Ternary Mixtures of Surfactant, Water, and Oil
Sammanfattning : An amphiphilic graft copolymer, with hydrophilic poly(ethylene glycol) monomethyl ether side chains grafted onto a hydrophobic poly(dodecyl methacrylate) backbone, has been synthesized. The side chains are water soluble and the backbone is soluble in oils such as cyclohexane and isooctane. LÄS MER
5. Preparation and Compatibilizing Properties of Poly(styrene-graft-ethylene oxide) in Polymer Blends
Sammanfattning : One of the main trends in the polymer industry today is the increasing importance of polymer blends. Combining two or more immiscible polymers in a polymer blend often leads to multi-phase materials with desirable properties. LÄS MER
