Title
(EN) POLYHEDRAL OLIGOMERIC SILSESQUIOXANE POLYURETHANES
(FR) POLYURÉTHANES CONTENANT UN OLIGOMÈRE POLYÉDRIQUE DE SILSESQUIOXANE
Abstract
(EN) A multi-block thermoplastic polyurethanes system which incorporates polyhedral oligomeric silsesquioxane into conventional biodegradable thermoplastic polyurethanes built up by poly(e-caproactone) and polyethylene glycol blocks, resulting in biostability. The multi-block thermoplastic polyurethanes are synthesized from lysine-diisocyanate with poly(8-caprolactone)-diol, polyhedral oligomeric silsesquioxane-diol, and poly(ethylene glycol) using a one-step synthesis process.
(FR) L'invention concerne un système de polyuréthanes thermoplastiques multi-séquencés qui incorpore un oligomère polyédrique de silsesquioxane dans des polyuréthanes thermoplastiques biodégradables classiques constitués de séquences de poly(e-caprolactone) et de polyéthylène glycol, permettant d'obtenir une biostabilité. Les polyuréthanes thermoplastiques multi-séquencés sont synthétisés à partir de diisocyanate de lysine et de poly(8-caprolactone)-diol, d'oligomère polyédrique de silsesquioxane-diol et de poly(éthylène glycol) au moyen d'un procédé de synthèse à une étape.
