Abstract: front page image
(EN)Disclosed is an ethylene oxide copolymer which is suppressed in increase of the glass transition temperature when a metal salt is added thereto. Also disclosed is a polymer composition of such an ethylene oxide copolymer. The ethylene oxide copolymer has a crystallization temperature of not more than 20˚C and a glass transition temperature or not more than -64˚C.
(FR)L'invention porte sur un copolymère d'oxyde d'éthylène pour laquelle est supprimée l'augmentation de la température de transition vitreuse lorsqu'un sel métallique lui est ajouté. L'invention porte également sur une composition de polymère d'un tel copolymère d'oxyde d'éthylène. Le copolymère d'oxyde d'éthylène a une température de cristallisation de pas plus de 20°C et une température de transition vitreuse ou de pas plus de -64°C.
(JA) 金属塩を加えた場合のガラス転移温度の上昇が少ないエチレンオキシド系共重合、並びにその重合体組成物を実現する。  本発明のエチレンオキシド系共重合体は、結晶化温度が20°C以下であり、かつガラス転移温度が-64°C以下である。
