2. Biodegradable Thermoplastic Elastomers
Abstract : 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. READ MORE

3. Structure Dependent Chemical and Biological Interactions of Poly(urethane urea)s
Abstract : Poly(urethane urea)s, PUURs, are widely used in both industrial and biological applications because of excellent physical and mechanical properties and good biocompatibility in a variety of applications. Both the processing and the tailoring of specific properties of PUUR demand great knowledge of structure-property relationships. READ MORE

5. Amphiphilic Polymers as Additives in Biomedical Polyurethanes. Surface Properties and Morphology
Abstract : The aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). READ MORE
