Abstract:
(EN) Provided are: a copolymer of 1, 3, 7-octatriene and isoprene which has a narrow molecular weight distribution (Mw/Mn); and a hydride thereof. Furthermore, provided is a method for producing the copolymer which includes structural units derived from 1, 3, 7-octatriene and structural units derived from isoprene, said method achieving a high raw material conversion rate in a short polymerization time. More specifically, the copolymer, which includes the structural units derived from 1, 3, 7-octatriene and the structural units derived from isoprene, has a molecular weight distribution (Mw/Mn) of less than 1.44.
(FR) L’invention fournit un copolymère de 1,3,7-octatriène et d’isoprène de répartition étroite de poids moléculaire (Mw/Mn) ainsi qu’un hybride de ce polymère. En outre, l’invention concerne un procédé de fabrication de ce copolymère comprenant une unité structurale dérivée d’un 1,3,7-octatriène et une unité structurale dérivée d’un isoprène, selon lequel un taux de conversion de matière première élevé est atteint en une courte durée de polymérisation. Ledit copolymère comprend de manière concrète une unité structurale dérivée d’un 1,3,7-octatriène et une unité structurale dérivée d’un isoprène, et présente une répartition de poids moléculaire (Mw/Mn) inférieure à 1,44.
(JA) 分子量分布(Mw/Mn)の狭い1,3,7-オクタトリエンとイソプレンの共重合体およびその水素化物を提供する。さらに、1,3,7-オクタトリエンに由来する構造単位とイソプレンに由来する構造単位とを含有する共重合体の製造方法において、短い重合時間で高い原料転化率を達成する。前記共重合体は、具体的には、1,3,7-オクタトリエンに由来する構造単位とイソプレンに由来する構造単位とを含有する共重合体であって、分子量分布(Mw/Mn)が1.44未満の共重合体などである。
