Abstract
(EN)
This polyalkylene ether glycol composition contains a polyalkylene ether glycol having an alkoxy group as a terminal group. The hydroxyl value of the polyalkylene ether glycol composition is 220-750. The ratio of the number of alkoxy group terminals of the polyalkylene ether glycol contained in the polyalkylene ether glycol composition with respect to the number of hydroxyl group terminals of the polyalkylene ether glycol contained in the polyalkylene ether glycol composition is 0.00001-0.0040. As a result, provided is a polyalkylene ether glycol composition that has excellent compatibility with low molecular weight polyols, that has excellent reactivity even when used a material for polyurethane, and that can exhibit desired physical properties.
(FR)
La composition de polyalkylène éther glycol selon l'invention contient un polyalkylène éther glycol ayant un groupe alcoxy en tant que groupe terminal. La valeur hydroxyle de la composition de polyalkylène éther glycol est de 220 à 750. Le rapport du nombre de terminaisons de groupe alcoxy du polyalkylène éther glycol contenu dans la composition de polyalkylène éther glycol par rapport au nombre de terminaisons de groupe hydroxyle du polyalkylène éther glycol contenu dans la composition de polyalkylène éther glycol est de 0,00001 à 0,0040. En conséquence, l'invention concerne une composition de polyalkylène éther glycol qui présente une excellente compatibilité avec des polyols de faible poids moléculaire, qui a une excellente réactivité même lorsqu'elle est utilisée comme matériau pour polyuréthane, et qui peut présenter des propriétés physiques souhaitées.
