  2. 6. Controllable degradation product migration from biomedical polyester-ethers

    Author : Anders Höglund; Ann-Christine Albertsson; Lars Wågberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; degradation products; ε-caprolactone; 1; 5-dioxepan-2-one; 6-hydroxyhexanoic acid; 3- 2-hydroxyethoxy propanoic acid; cross-linking; inflammatory response; Polymer chemistry; Polymerkemi;

    Abstract : The use of degradable biomedical materials has during the past decades indeed modernized medical science, finding applications in e.g. tissue engineering and drug delivery. The key question is to adapt the material with respect to mechanical properties, surface characteristics and degradation profile to suit the specific application. READ MORE

    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

  7. 10. Synthesis of End-functionalized Polyesters byRing-Opening Polymerization of ε-Caprolactone

    Author : Jessica Schröder; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

    Abstract : The main objective of this work was to investigate the ring-opening polymerizations of cyclic esters by enzyme catalysis and cationic activated monomer polymerization in the search for new polymer materials and fiber-based composites. Candida antarcica lipase B was used for end-functionalization of poly(ε-caprolactone) and in the copolymerization of D,L-lactide and ε-caprolactone. READ MORE
