Abstract

The expansion of the range of available and reactive monomers allowing preparation of novel polymeric materials, is an actual task of polymer chemistry. This mini-review is devoted to the polymerization of tricyclo [4.2.1.0^2,5]non-7-enes (tricyclononenes) and tricyclo[4.2.1.0^2,5]nona-3,7-dienes (tricyclonona-dienes)–norbornene type monomers containing norbornene and cyclobutane or cyclobutene fragments in the molecules. Their synthesis is carried out using available cyclopentadiene or quadricyclane, which is a product of norbornadiene photo-isomerization. The features of ring-opening metathesis and addition polymerization of tricyclononenes with participation of double bond in the norbornene fragment are highlighted. Examples of the polymerization of a wide range of tricyclononenes with F-, Si-, O-, and N-containing substituents have demonstrated that they are noticeably more active monomers than norbornenes with the same substituents. The main successes have been achieved in the synthesis of F- and Si-substituted polytricyclononenes, which are promising materials for lithography and membrane gas separation.

三环壬烯的聚合

抽象的

扩大可用和反应性单体的范围以允许制备新颖的聚合物材料是聚合物化学的实际任务。这份小型综述专门讨论三环[4.2.1.0 ^2,5 ]非-7-烯（tricyclononenes）和三环[4.2.1.0 ^2,5 ]的聚合] nona-3,7-二烯（三环壬二烯）-降冰片烯型单体，分子中含有降冰片烯和环丁烷或环丁烯片段。它们的合成是使用环戊二烯或四环烷进行的，环戊二烯或四环烷是降冰片二烯光异构化的产物。突出了降冰片烯片段中双键参与的三环壬烯的开环易位和加成聚合的特征。范围广泛的具有F-，Si-，O-和N取代基的三环壬烯的聚合反应实例表明，与具有相同取代基的降冰片烯相比，它们明显更具活性。在合成F-和Si-取代的聚三环壬烯方面已经取得了主要成功，F-和Si取代的聚三环壬烯是用于光刻和膜气体分离的有前途的材料。
