基于内异构体和外异构体反应性的差异，探讨了功能降冰片烯开环歧化聚合过程中单体序列的潜在控制。这种动力学方法允许快速消耗外降冰片烯，并在整个聚合物链的狭窄区域内插入到不断增长的聚(降冰片烯)链上，同时保持均一的主链。我们在这里证明，这可以使用一系列功能单体来实现，这些单体很容易从商业上可获得的前体中衍生出来，同时它们的聚合是以受控的方式进行的。
The potential control over monomer sequence in the ring-opening metathesis polymerization of functional norbornenes is explored based on the difference in reactivity of endo and exo isomers. This kinetic approach allows the rapid consumption of the exo-norbornene and insertion onto the growing poly(norbornene) chain within a narrow region of the overall polymer chain, whilst maintaining a homogeneous backbone. We herein demonstrate that this can be achieved using a range of functional monomers easily derived from commercially available precursors while their polymerization is carried out in a controlled manner.
