  5. 5. Synthesis of Biomedical Polymers and Scaffold Design

    Detta är en avhandling från Stockholm : KTH

    Författare :Therese Tyson; Ann-Christine Albertsson; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; tin alkoxide initiator; stannous octoate; poly p-dioxanone ; copolymer; L-lactide; trimethylene carbonate; degradable porous scaffold; NATURAL SCIENCES Chemistry Organic chemistry Polymer chemistry; NATURVETENSKAP Kemi Organisk kemi Polymerkemi;

    Sammanfattning : This work has focused on the development of new improved synthesis methods of biodegradable aliphatic polymers and on the preparation of porous scaffolds for tissue engineering applications. The aim of the first part of the work was the synthesis of poly(p-dioxanone) (PPDX) homopolymers with high molecular weights using the cyclic tin alkoxide initiator 1-di-n-butyl-1-stanna-2,5-dioxacyclopentane.
