  1. 1. Development Of Bio-Based Thermosetting Resins

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Jonas Lindman; [2016]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 3. Biodegradable Composites : Processing of thermoplastic polymers for medical applications.

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Behzad Damadzadeh; Hamideh Jabari; [2009]
    Nyckelord :poly lactic acid; poly glycolic acid; microcompounder; in-vitro degradation; biomedical application; hydroxy appetite hap ; tricalcium phosphate tcp ; bioactive glass bag ; bioceramic; medical composite; differential scanning calorimetry dsc ; inherent viscosity; termogravimetric analysis tga ; scanning electron microscopy sem ; biodegradable composite;

    Sammanfattning : Despite the recent development in PLA and PLGA based medical devices, there are still needs to further improve the mechanical performance of bioresorbable medical implants and their bioactivity. This is normally done by optimizing the filler compositions in selected groups ofbiodegradable polymer matrices. LÄS MER
