Abstract This project aims the synthesis of segmented and amphiphilic polyurethanes, potentially biodegradable and biocompatible based on poly(L-lactide) (PLLA) and poly(2-ethyl-2-oxazolyne) (PEtOx). The PLLA is a hydrophobic polymers, while PEtOx is a hydrophilic polymers, which aqueous solutions present LCST phase behavior and properties dependent on the pH and temperature. Depending on the composition, these polyurethanes can swell in water without solubilize, producing hydrogels in which the hydrophobic PLLA segments act as crosslinker. The polyurethanes will be characterized according to composition, thermal and mechanical properties, water swelling capability and its dependence on the pH and temperature. (AU) | |
