3. 7. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Tobias Lindborg; [2022]
   Keywords : Lignin; Polymer; Renewable; Bioresource; Glass transition temperature; Nitrile; Polymer technology; Chemistry; Technology and Engineering;

   Abstract : 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. READ MORE

4. 8. Functional Bio-based Copolyesters: Properties and Abilities

   University essay from KTH/Fiber- och polymerteknologi

   Author : Fika Andriani; [2022]
   Keywords : Ring-opening copolymerization; epoxide; anhydride; crosslinked; degradation; Ringöppningssampolymerisation; epoxid; anhydrid; tvärbundet; nedbrytning;

   Abstract : Genom ringöppningssampolymerisation av utvalda epoxider och anhydrider möjliggjordes en enkel strategi för att syntetisera funktionella sampolymerer. Sampolymererna hade förmågan att bilda tvärbundna material, och var dessutom benägna för både hydrolytisk och enzymatisk nedbrytning. READ MORE

5. 9. Modelling the global water cycle – the effect of Mg-sursassite on the amount of globally subducted water

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Nils Benjamin Gies; [2021-07-05]
   Keywords : ;

   Abstract : Subduction of hydrated lithospheric mantle is the most important process regarding the transfer of significant amounts of water to depths exceeding 350 km. Hence, the interplay of the thermal structure within the subducted slab together with the PT-stability fields of hydrous ultra-high pressure phases control the dehydration of the slab and the amount of water transported into the deeper mantle.

6. 10. Novel materials from lignocellulosic sources- can they replace thermoplastics?

   University essay from KTH/Fiber- och polymerteknologi

   Author : Emmy Albinsson; Helina Tafesse Belachew; Jasmin Swaich; Hannah Juhlin; [2021]
   Keywords : Emulisonspolymerisation; Biobaserade plaster; Hållbarhet; Polymerer; Bearbetad halm; Kompositer; PISA-raft;

   Abstract : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. READ MORE
