Title

(FR) POLYURÉTHANE THERMOPLASTIQUE AINSI QUE PROCÉDÉ ET ARTICLE ASSOCIÉS
Abstract
(EN)
A thermoplastic polyurethane is formed by the reaction of a specific hydroxy-diterminated poly(phenylene ether) and an organic diisocyanate. The polyurethaneforming reaction optionally employs diols other than the hydroxy-diterminated poly(phenylene ether). Compared to thermoplastic polyurethanes lacking the residue of the hydroxy-diterminated poly(phenylene ether), the thermoplastic polyurethanes described herein exhibit properties including one or more of improved heat and oxidation resistance, improved resistance to acids, bases, and solvent, and reduced water absorption.
(FR)
L'invention concerne un polyuréthane thermoplastique formé par réaction d'un poly(phénylène éther) spécifique à deux terminaisons hydroxy et d'un diisocyanate organique. La réaction de formation du polyuréthane utilise éventuellement des diols autres que le poly(phénylène éther) à deux terminaisons hydroxy. Par rapport aux polyuréthanes thermoplastiques sans résidu de poly(phénylène éther) à deux terminaisons hydroxy, les polyuréthanes thermoplastiques décrits ici présentent des propriétés telles que la résistance à la chaleur et à l'oxydation, une plus grande résistance aux acides, aux bases et aux solvants, et une réduction de l'absorption d'eau.
