| 제목 | Mechanism of Polymerization of Isocyanate by Sodium benzanilide (Na-BA) |
| 초록 | Since Shashoua first reported the polymerization of isocyanates with sodium cyanide in dimethylformamide in 1959, many researchers have studied the synthesis of polyisocyanates. One of the limitation factor in living polymerizations of isocyanates is depolymerization by the formation of trimer. We recently achieved the living anionic polymerization of isocyanates with sodium naphthalenide (Na-Naph) as an initiator using additives such as 15-crown-5 and sodium tetraphenylborate (NaBPh4). In this study, n-hexyl isocyanate (HIC) was polymerized with changing reaction time via anionic polymerization with sodium bezanilide (Na-BA) In THF at -98 ℃. The experimental details and the results will be presente Fig. 1. Mechanism of Polymerization of Isocyanate by Sodium benzanilide (Na-BA) 참고문헌 1.S.-W. Ryu and J.-S.
