Abstract—

Using the commercial derivative of norbornene—5-ethylidene-2-norbornene—a series of three isomeric homopolymers with different structure of the backbone is synthesized, and the effect of the chain structure on the gas-transport behavior of polynorbornenes is studied. The gas-transport characteristics of the polymers are presented together with data on the conformation properties of molecules of addition and metathesis polynorbornenes. The effect of the structure of side substituents on the equilibrium rigidity of addition polynorbornenes is confirmed by the example of poly(5-ethylidene-2-norbornene) and poly(5-vinyl-2-norbornene).

基于5-乙叉-2-降冰片烯和5-乙烯基-2-降冰片烯的均聚物的合成，分子和气体传输性质

摘要—

利用降冰片烯的商品衍生物5-亚乙基-2-降冰片烯，合成了一系列具有不同骨架结构的三种异构体均聚物，研究了链结构对聚降冰片烯气体输运行为的影响。给出了聚合物的气体传输特性，以及有关加成和复分解聚降冰片烯分子的构象特性的数据。通过聚（5-亚乙基-2-降冰片烯）和聚（5-乙烯基-2-降冰片烯）的实例证实了侧取代基的结构对加成聚降冰片烯的平衡刚性的影响。
