In a topochemical reaction, chemical changes start at active sites in the solid and then proceed autocatalytically to neighboring regions. If one starts with a monomer that can form ordered structures similar to the final polymer, it is possible to polymerize chains in a fully ordered state and thus make very long single chains.
在拓扑化学反应中,化学变化始于固体中的活性位点,然后自催化地向相邻区域进行。如果使用能够形成类似最终聚合物有序结构的单体,则可以在完全有序的状态下聚合链,并制备非常长的单一聚合链。
