  2. 1. Polyesters with indole as sustainable aromatic component

    Author : Ping Wang; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; indole; sustainable polyesters; high performance; recycling; biodegradation;

    Abstract : Plastics are widely used in our daily lives and industry. Unfortunaltely, most plastics are produced from non-renewable fossil resources. The transition toward sustainable resources such as various biomass is critically important for the future of plastic industry and the whole society. READ MORE

  4. 2. Toward Biomass-Derived Recyclable Polyesters

    Author : Smita Vamdev Mankar; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyester; polycondensation; spiroacetal; chemical recycling; enzymatic degradation;

    Abstract : Fossil-based plastics have become a matter of concern due to their negative environmental impacts such as greenhouse gas emissions and threats to the health of living beings. Alternative polymers derived from sustainable biomass resources have thus become an attractive research field since the last decade. READ MORE

  5. 3. Towards a retro-structural design of degradable aliphatic polyester-based materials

    Author : Veluska Arias; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrolysis; polyesters; polylactide; hydrophobicity; crystallinity; miscibility; nanoparticles; stereocomplex; homocomposites; Kemi; Chemistry;

    Abstract : The increasing amount of accumulated plastic waste has led to a continuous search for degradable materials for use in a variety of applications. This eco-friendly approach contemplates the use of degradable alternatives to the inert polymers (the main components in plastics) used today and further engineering of their degradation pathways.

  6. 4. Exploring different thermoplastics from lignocellulosic building blocks and monomers

    Author : Olivier Bonjour; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biobased plastics; Biobased polymers; Polymethacrylates; Polycarbonates; Polyesters; Poly beta-thioether ester s; Chemical recycling; Biobased plastics; Biobased polymers; Polycarbonates; Polymethacrylates; Poly beta-thioether ester s; Polyesters; Chemical recycling;

    Abstract : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. READ MORE

  7. 5. Thiol−ene Coupling of Renewable Monomers : at the forefront of bio-based polymeric materials

    Author : Mauro Claudino; Mats K. G. Johansson; Mats Jonsson; Anna Wistrand; Sven Göthe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; monounsaturated fatty-acids; renewable resources; cis trans-isomerization; photopolymerization; networks; polyesters; thermal viscoelastic properties; thin-films; unsaturated macro lactones; coatings;

    Abstract : Plant derived oils bear intrinsic double-bond functionality that can be utilized directly for the thiol–ene reaction. Although terminal unsaturations are far more reactive than internal ones, studies on the reversible addition of thiyl radicals to 1,2-disubstituted alkenes show that this is an important reaction.
