This study present new polyetherurethanes (PEU) based on cellulose derivative, allowing for their application for medical devices. The polyurethane samples were synthesized from polytetramethyleneetherglycol (PTMEG), as macrodiol, 1,6-hexamethylene diisocyanate (HDI), 4,4’-methylene bis(cyclohexyl isocyanate) (HMDI), isophorone diisocyanate (IPDI), as diisocyanate components and hydroxypropyl cellulose (HPC) as chain extender, by the one-shot process without catalyst. The properties of these materials, such as water vapours sorption capacity, contact angles, thermal, mechanical and dielectrical behaviour have been evaluated with respect to their structure. By careful selection of polyurethane composition it is possible to design a range of polymers, which may have great potential in tissue engineering applications..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
