1. Synthesis and characterization of lactic acid-based elastomers
University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomiAbstract : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

2. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals
University essay from KTH/KemiteknikAbstract : 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. READ MORE

3. ROP in novel biobased ionic liquids towards cellulose functionalization
University essay from KTH/Fiber- och polymerteknologiAbstract : Ett nytt sätt att aktivera cellulosa för kemisk modifiering med hjälp av en miljövänlig process har utvecklats innan starten av detta projekt. Två versionen av den nyskapade betain-baserade jonvätskan, BBIL har syntetiserats, en som använder mesylat som motjon, M-BBIL och en som använder acetat, A-BBIL. READ MORE

4. Functional Bio-based Copolyesters: Properties and Abilities
University essay from KTH/Fiber- och polymerteknologiAbstract : 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. Development Of Bio-Based Thermosetting Resins
University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomiAbstract : Thermoset polymers are widely used polymers in the world, but Increase in global plastic pollution and lack of fossil fuel stimulates intense research towards environmentally sustainable materials. Bio-based unsaturated polyesters (UPs) would be an excellent solution to replace oil-based synthetic polyesters. READ MORE
