    Sammanfattning : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

  5. 4. Synthesis and [3,3]-Sigmatropic Rearrangement of Vinylaziridines

    Författare :Ulf Lindström; Torbjörn Frejd; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : A general synthetic route from vinylepoxides to vinylaziridines via 1,2-amino alcohols was developed. The 1,2-amino alcohols were obtained from a stereospecific and regioselective aminolysis of vinylepoxides. The synthetic scope of the aminolysis could be expanded by the use of a microwave-assisted protocol. LÄS MER

  7. 5. Designed from Recycled: Microwave-Assisted Upcycling of Plastic Waste

    Författare :Eva Bäckström; Minna Hakkarainen; Karin Odelius; Antal Boldizar; KTH; []
    Nyckelord :Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Mismanagement of plastic waste is of great concern. To reach a more sustainable society, methodologies to handle materials in a more circular way needs to be developed. LÄS MER
