  具有聚（2-金刚烷基乙烯基醚）和聚（正丁基乙烯基醚）链段的ABA-三嵌段和星形二嵌段共聚物的合成：仅由聚（乙烯基醚）主链组成的新型热塑性弹性体

  摘要：

  ABA型三嵌段共聚物和AB型星二嵌段共聚物与聚（2-金刚烷基乙烯基醚）[聚（2- AdVE）]硬外段和聚（Ñ通过连续活性阳离子共聚合成了丁基丁基醚）[聚（NBVE）]软内链段。尽管两个聚合物链段均仅由聚乙烯醚主链和烃侧链组成，但它们均被分离成微相分离的结构，因此嵌段共聚物形成了热塑性弹性体。ABA型三嵌段共聚物和AB型星形二嵌段共聚物在宽温度范围内均显示出橡胶弹性。例如，ABA型三嵌段共聚物的橡胶弹性为约-53°C至165°C，而AB型星形二嵌段共聚物的橡胶弹性为约-47°C至183°C，且聚（2 ‐AdVE）和poly（NBVE）段在动态力学分析中。与ABA型三嵌段共聚物相比，AB型星形二嵌段共聚物具有更高的拉伸强度和断裂伸长率。两种嵌段共聚物的热分解温度均高达321–331°C，表明它们具有很高的热稳定性。©2013 Wiley Periodicals，Inc.

  The ABA‐type triblock copolymers consisting of poly(2‐adamantyl vinyl ether) [poly(2‐AdVE)] as outer hard segments and poly(6‐acetoxyhexyl vinyl ether) [poly(AcHVE)], poly(6‐hydroxyhexyl vinyl ether) [poly(HHVE)], or poly(2‐(2‐methoxyethoxy)ethyl vinyl ether) [poly(MOEOVE)] as inner soft segments were synthesized by sequential living cationic polymerization. Despite the presence of polar functional

  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.
