Title (EN) METHOD FOR PRODUCING ISOBUTYLENE POLYMER
(FR) PROCÉDÉ DE FABRICATION DE POLYMÈRE À BASE D’ISOBUTYLÈNE
(JA) イソブチレン系重合体の製造方法
Abstract:
(EN) The present invention addresses the problem of clarifying the polymerization control effect of (meth)acrylic acid esters which heightens the living property and, by using the same, suppressing secondary reactions and providing a method for obtaining an isobutylene polymer having small molecular weight distribution Mw/Mn. The present invention relates to a method for producing an isobutylene polymer characterized in that living cationic polymerization of isobutylene is carried out in the presence of a polymerization initiator, a polymerization catalyst, and a (meth)acrylic acid ester compound.
(FR) L’invention a pour objet de fournir un procédé destiné à obtenir un polymère à base d’isobutylène dont les effets de régulation de polymérisation d’un ester d’acide (méth)acrylique accroissant les propriétés vivantes, sont clairs, et qui ainsi évite les réactions secondaires, et présente une faible répartition de poids moléculaire (Mw/Mn). Plus précisément, l’invention concerne un procédé de fabrication de polymère à base d’isobutylène qui est caractéristique en ce qu’une polymérisation cationique vivante d’un isobutylène, est effectuée en présence d’un initiateur de polymérisation, d’un catalyseur de polymérisation et d’un composé ester d’acide (méth)acrylique.
(JA) 本発明は、リビング性を高める(メタ)アクリル酸エステルの重合制御効果を明らかにし、これを用いることによって、副反応を抑制し、分子量分布Mw/Mnが小さいイソブチレン系重合体を得るための方法を提供することを課題とする。本発明は、重合開始剤、重合触媒、および(メタ)アクリル酸エステル化合物の共存下で、イソブチレンのリビングカチオン重合を行うことを特徴とするイソブチレン系重合体の製造方法に関する。
