Title
(EN) POLYOXYALKYLENE POLYMER AND CURABLE COMPOSITION
(FR) POLYMÈRE DE POLYOXYALKYLÈNE ET COMPOSITION DURCISSABLE
(JA) ポリオキシアルキレン系重合体及び硬化性組成物
Abstract
(EN)
A polyoxyalkylene polymer which has the main chain structure of a polyoxyalkylene and a terminal structure that is bonded to an end of the main chain structure, and which is configured such that: the terminal structure has a hydrolyzable silyl group and a terminal olefin group and/or an inner olefin group; the total number of the hydrolyzable silyl group, the terminal olefin group and the inner olefin group is more than 1.0 on average per one terminal structure; and the value of (the number of moles of the hydrolyzable silyl groups)/(the total number of moles of the hydrolyzable silyl groups, the terminal olefin groups and the inner olefin groups) in the polyoxyalkylene polymer is from 0.3 to 0.7.
(FR)
L'invention concerne un polymère de polyoxyalkylène qui présente la structure de chaîne principale d'un polyoxyalkylène et une structure terminale qui est liée à une extrémité de la structure de chaîne principale, et qui est conçu de telle sorte que : la structure terminale présente un groupe silyle hydrolysable et un groupe oléfine terminal et/ou un groupe oléfine interne ; la somme des nombres du groupe silyle hydrolysable, du groupe oléfine terminal et du groupe oléfine interne soit supérieure à 1,0 en moyenne par structure terminale ; et la valeur de (le nombre de moles des groupes silyle hydrolysable)/(la somme des nombres de moles des groupes silyle hydrolysable, des groupes oléfine terminaux et des groupes oléfine internes) dans le polymère de polyoxyalkylène soit de 0,3 à 0,7.
(JA)
ポリオキシアルキレンの主鎖構造と、該主鎖構造の末端に結合した末端構造を有するポリオキシアルキレン系重合体であって、該末端構造が、加水分解性シリル基と、末端オレフィン基及び/又は内部オレフィン基とを有し、加水分解性シリル基、末端オレフィン基及び内部オレフィン基の合計数が、末端構造1個あたり平均して1.0より多く、前記ポリオキシアルキレン系重合体における加水分解性シリル基のモル数/(加水分解性シリル基、末端オレフィン基及び内部オレフィン基の合計モル数)が0.3~0.7である。
