1. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals
Kandidat-uppsats, KTH/KemiteknikSammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER
2. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. LÄS MER
3. Modification of lignin derivatives for polymerization in water
Master-uppsats, KTH/YtbehandlingsteknikSammanfattning : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. LÄS MER
4. Ferulic Acid – A Valuable Natural Compound for Sustainable Materials
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : One of the largest problems that stands before us is the quest to find sustainable alternatives to fossil-based materials. Fossil-based products can be found all around us in our society. This quest has forced us to look for new ways to build materials. LÄS MER
