  2. 1. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

    Author : Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Abstract : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. READ MORE

  4. 2. Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

    Author : Amin Bornadel; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Abstract Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in non-conventional reaction media. READ MORE

    Abstract : The regeneration of damaged tissues or organs using porous scaffolds which act as temporary guides for the patient’s own cells, i.e. tissue engineering, is a means to overcome the shortcomings of current standard medical treatments. READ MORE

  6. 4. Thermodynamic Toolkit for Chemical Recycling to Monomer

    Author : Linnea Cederholm; Karin Odelius; Minna Hakkarainen; Peter Olsen; Louis Pitet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemical recycling to monomer; polymerization thermodynamics; ring-opening polymerization; solvent effect; polyester; polycarbonate; copolymer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The design of polymeric materials for a circular economy is, to a largeextent, a challenge of thermodynamics. The work presented in this thesishas explored the thermodynamic features of ring-opening polymerizationand ring-closing depolymerization, to develop polymeric materials andrecycling strategies for chemical recycling to monomer.
