Synthetic Route
| It is formed by the polymerization of the monomer 9-ethylene, which is polymerized at a low temperature of -70~10℃, and obtained by cationic polymerization initiated by free radicals; however, it is polymerized at 5~10℃ to obtain poly-9,10-dimethylenanthrene or poly-9-vinylenanthrene. |
