1. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications
Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER
2. Branched aliphatic polycarbonates : synthesis and coating applications
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.

3. Exploring different thermoplastics from lignocellulosic building blocks and monomers
Sammanfattning : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. LÄS MER
4. Versatile Synthetic Strategies to Highly Functional Polyesters and Polycarbonates
Sammanfattning : Polymers have become ubiquitous in today’s society and are found in everything from household items to airplanes and automobiles. Synthetic polymeric materials are as diverse as their applications and their final properties are highly reliant on the building blocks and methods used to assemble them. LÄS MER
5. Cation Conduction and Coordination in Carbonyl-Containing Compounds : Li+ Transport in Alternative Polymer Electrolyte Host Materials
Sammanfattning : The field of solid polymer electrolytes (SPEs) used to create safer lithium-ion batteries has been dominated by polyethylene oxide (PEO) since the discovery of its ion-conducting properties in the 1970s. In this thesis, as an alternative, the ion coordination and conduction properties of SPEs based on polyketones, polyesters and polycarbonates are investigated. LÄS MER
