  1. 1. Development Of Bio-Based Thermosetting Resins

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Snehaben Gaurangkumar Mistry; [2021]
    Keywords : Bio-based polymer; Resin; lactide; lactone; isosorbide; butanediol; polymerisation; characterisation; FTIR; NMR; TGA; DMA;

    Abstract : 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

  3. 2. Synthesis of functional polylactide : Monomer synthesis scale-up and poly(ethylene glycol) functionalization

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jonas Lindman; [2016]
    Keywords : ;

    Abstract : This master’s degree project optimized the synthesis route to a functional lactide by increasing the total yield from 25 to 33 % and reducing the number of unit operations from 17 to 10. This was done by optimizing an existing synthetic pathway to better fit larger scale manufacturing. READ MORE
