在试图通过开环易位聚合在不断增长的聚异戊二烯中引入单体序列控制时，我们采用二氧杂环庚三烯来有效地确定大分子主链上单体的位置。由于酸不稳定的缩醛基团，二氧杂环庚三烯允许聚合物在二氧杂环庚三烯插入点断裂，从而提供了一种间接的方法来确定单体的位置。此外，二氧杂环庚三烯在多嵌段聚异戊二烯的合成中用作间隔基，所述多嵌段聚异戊二烯容易裂解以提供单独的聚异戊二烯嵌段。(C)2015年威利期刊公司
In an attempt to introduce monomer sequence control in a growing polynorbornene via ring-opening metathesis polymerization, we employ dioxepins to efficiently determine the location of the monomers on the macromolecule backbone. Owing to the acid-labile acetal group, dioxepins allow scission of the polymer at the point of the dioxepin insertion and thus provide an indirect way to determine the monomer location. Additionally, dioxepins are used as spacers in the synthesis of multiblock polynorbornenes that are readily cleavable to afford the individual polynorbornene blocks. (C) 2015 Wiley Periodicals, Inc.
