CA 2556196

An object of the present invention is to provide a polyether composition that can suppress reduction in a molecular weight of polyether having a low glass transition temperature and melting point. As a means of achieving this object, a polyether composition of the present invention contains polyether having a glass transition temperature of -50 oC or lower and a melting point of 55 oC or lower and, at the same time, contains at least one kind selected from the group consisting of compounds represented by the specified three general formulas.

Un but de la présente invention est de fournir une composition à base de polyéther qui puisse supprimer la diminution au niveau d~une masse moléculaire de polyéther ayant une température de transition vitreuse et une température de fusion faibles. En tant que moyen pour atteindre ce but, une composition à base de polyéther de la présente invention contient un polyéther qui a une température de transition vitreuse de -50·C ou inférieure et une température de fusion de 55·C ou inférieure et, en même temps, contient au moins un genre de composé sélectionné parmi le groupe constitué des composés représentés par les trois formules générales précisées.
