can be crosslinked at 100–150 °C. The 4- and 5-vinyl isomers are synthesized in a 1:4 ratio via a halogenated benzyne intermediate produced from anthranilic acid, followed by cycloaddition with ethyl vinyl ether and replacement of the halogen atom with a vinyl group.
1-乙氧基乙烯基苯并环丁烯是一种取代的苯并环丁烯,经过自由基聚合生成可在 100–150 °C 下交联的聚合物。4- 和 5- 乙烯基异构体通过由邻氨基苯甲酸生产的卤化苄中间体以 1:4 的比例合成,然后与乙基乙烯基醚环加成并用乙烯基取代卤素原子。
