  1. 1. Biodegradable Thermoplastic Elastomers

    Författare :Basse Asplund; Jöns Hilborn; Tim Bowden; Iskender Yilgör; Uppsala universitet; []
    Nyckelord :Chemistry; poly urethane ; poly urethane urea ; biomaterial; biodegradable; polymer; thermoplastic elastomer; haemocomatible; tissue engineering; biocompatible; Kemi;

    Sammanfattning : A novel strategy for synthesising segmented poly(urethane urea) (PUU) without using a chain extender but nevertheless with the opportunity to vary the hard segment content has been developed. The strategy is based on amine formation from isocyanate upon reaction with water. LÄS MER

  3. 2. Bioresorbable copolymers with tailored properies : innovative materials för soft tissuel engineering

    Författare :Natalia Andronova; Ann-Christine Albertsson; Pieter Dijkstra; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; poly 1; 5-dioxepan-2-one ; poly ε-caprolactone ; poly L-lactide ; poly trimethylene carbonate ; triblock; network; cyclic tin alkoxide; controlled coordination-insertion ring-opening polymerization; thermoplastic elastomers; Polymer chemistry; Polymerkemi;

    Sammanfattning : The emerging need for new synthetic materials for soft tissue engineering applications encourages the search for innovative polymers having interesting properties. Ring-opening polymerization of lactones and lactides initiated by tin alkoxides has received particular attention due to the versatility of the method for building up well-defined biodegradable structures.
