  2. 16. Macromolecular design and architecture of aliphatic polyesters

    Author : Karin Odelius; Ann-Christine Albertsson; Helmut Keul; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ring-opening polymerization; L-lactide; 1; 5-dioxepane-2-one; ε-caprolactone; Polymerization kinetics; Star-shaped architecture; Spirocyclic tin initiator; Polymer chemistry; Polymerkemi;

    Abstract : Public health care has reached a level where tissue or organ reconstruction by means of biodegradable short-term implants via e.g. tissue engineering will be practicable in the near future. READ MORE

  4. 17. Synthetic Pathways to Aliphatic Polyesters and Scaffold Design

    Author : Therese Tyson; Ann-Christine Albertsson; Elisabetta Ranucci; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : As the field of tissue engineering progresses, a continuous development of scaffold fabrication techniques and suitable degradable materials is required to obtain scaffolds with tunable characteristics. This thesis has focused on the development of pathways to synthesize degradable aliphatic polyesters and on the design of highly porous scaffolds from this class of materials. READ MORE

  5. 18. Utilizing lignocellulose-based building blocks to develop recyclable polyesters

    Author : Nitin Valsange; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biobased; Polyester; Recycling;

    Abstract : With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. READ MORE

  6. 19. Versatile Synthetic Strategies to Highly Functional Polyesters and Polycarbonates

    Author : Daniel Hult; Michael Malkoch; Andrew Dove; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Polymers have become ubiquitous in today’s society and are found in everything from household items to airplanes and automobiles. Synthetic polymeric materials are as diverse as their applications and their final properties are highly reliant on the building blocks and methods used to assemble them. READ MORE

  7. 20. Crystallisation of star polyesters with poly (ε-caprolactone) arms : approaching the problem of early stages in polymer crystallisation

    Author : Eugenia Núñez; KTH; []
    Keywords : Technology; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The knowledge regarding early stages in polymer crystallisation remains inconclusive due to experimental limitations. The reason is that the initially formed polymer crystals rearrange rapidly at the crystallisation temperature. Faster experimental techniques or simulation would be suitable alternatives to approach the problem. READ MORE
