  7. 5. Synthesis of functional degradable polymers by radical ring-opening polymerization

    Författare :Jenny Undin; Ann-Christine Albertsson; Mats Johansson; Monica Ek; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tissue engineering; ring-opening polymerization; 2; 2´-azoisobutyronitrile; cyclic ketene acetals; 2-methylene- 1; 3; 6-trioxocane; 2-methylene- 1; 3-dioxepane; vinyl acetate; coopolymerization;

    Sammanfattning : The increased demand for understanding cell-material interactions and subsequently create personalized implants for tissue engineering has resulted in an increased interest in developing new monomers with functional groups. The focus of the work presented in this thesis has been on the synthesis of functional monomers and the polymerization of these into functional amorphous aliphatic polyesters. LÄS MER
