研究了亚胺CN单体的合成和聚合性能。所研究的亚胺要么比类似取代的 CC 或 CO 单体更具反应性，要么太稳定而无法聚合。 N上带有吸电子取代基的亚胺有利于通过阴离子机理进行聚合，但仅产生低分子量聚合物。 N上具有供体取代基的亚胺，例如N-芳基亚甲基亚胺，通过阳离子或阴离子机理聚合。 1-和2-氮杂-1,3-丁二烯也相当不稳定并聚合成低聚物。对称取代的 2,3-二氮杂-1,3-丁二烯可以使用阴离子引发剂成功纯化和聚合，根据取代基在聚合物主链中产生 1,4- 和 1,2- 结构。 © 2012 Wiley periodicals, Inc.

The synthesis and polymerizability of imine CN monomers is surveyed. The investigated imines were either far more reactive than similarly substituted CC or CO monomers, or too stable to polymerize. Imines with electron-attracting substituents on N favor polymerization by anionic mechanism, but led only to low molecular weight polymers. Imines with a donor substituent on N, such as N-arylmethyleneimines, polymerized by cationic or anionic mechanism. 1- and 2-Aza-1,3-butadienes were also rather unstable and polymerized to oligomers. The symmetrically substituted 2,3-diaza-1,3-butadienes could be purified and polymerized successfully using anionic initiators, resulting in both 1,4- and 1,2-structures in the polymer backbone, depending on the substituents. © 2012 Wiley Periodicals, Inc.
