To provide a novel ABA-type triblock copolymer of vinyl ether series, comprising polyvinyl ether and an oxystyrene-series unit, and a process of producing the ABA-type copolymer at a series of steps. The invention relates to a novel ABA-type triblock copolymer comprising Segment A comprising an oxystyrene-series repeat unit (a) and Segment B comprising a vinyl ether-series repeat unit (b), in which the Segment A and the Segment B are bonded together with a single bond, and to a simple process of producing the same. The triblock copolymer can be produced at a series of steps in a simple manner, comprising living cationic polymerization of a vinyl ether-series monomer such as ethyl vinyl ether in the presence of a bifunctional initiator and a Lewis acid, and subsequently adding an oxystyrene-series monomer such as p-hydroxystyrene for living cationic polymerization.
提供一种新型 ABA 型乙烯基醚系列三嵌段共聚物,该共聚物由聚乙烯醚和氧苯乙烯系列单元组成,并提供一种通过一系列步骤生产该 ABA 型共聚物的工艺。本发明涉及一种新颖的 ABA 型三嵌段共聚物,它由包含氧苯乙烯系列重复单元 (a)的段 A 和包含乙烯基醚系列重复单元(b)的段 B 组成,其中段 A 和段 B 以单 键结合在一起,本发明还涉及生产这种共聚物的简单工艺。三嵌段共聚物可以通过一系列简单步骤生产,包括在双官能团引发剂和路易斯酸存在下,乙烯基醚系列单体(如乙基乙烯基醚)的活阳离子聚合,然后加入氧基苯乙烯系列单体(如对羟基苯乙烯)进行活阳离子聚合。
