1. Investigation of acidic chemical recycling of poly(acetal-ester)s
Magister-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER
2. 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
3. Bio-based resins for digital light processing : Mechanical and degradable properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

4. Functional Bio-based Copolyesters: Properties and Abilities
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : 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. LÄS MER
5. Glucose Levulinates as Bio-plasticizers
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Glucose, as the most plentiful sugar in nature, is a renewable resource and possesses excellent record in health safety. Levulinic acid is a platform chemical which plays an important role in biomass transformation and reactive intermediates. LÄS MER
