Abstract
A multi-block thermoplastic polyurethanes system which incorporates polyhedral oligomeric silsesquioxane into conventional biodegradable thermoplastic polyurethanes built up by poly(ε-caproactone) and polyethylene glycol blocks, resulting in biostability. The multi-block thermoplastic polyurethanes are synthesized from lysine-diisocyanate with poly(ε-caprolactone)-diol, polyhedral oligomeric silsesquioxane-diol, and poly(ethylene glycol) using a one-step synthesis process.
