| 摘 要： | 研究了萘-锂-四氢呋喃(THF)络合反应体系及齐聚二烯烃双锂引发剂的稳定性。结果表明:萘-锂-THF络合物与萘-钠-THF结构相似,但络合反应更易;齐聚二烯烃双锂引发剂的稳定性受温度、THF浓度的影响;聚丁二烯双锂较聚异戊二烯双锂稳定,单锂化反应严重影响着引发剂的官能度。

| Abstract: | Li-naphthalene complex, compared to Na-naphthalene, was formed more easily and had similar construction in THF, The stability of oligomeric diene dilithium was imfluenced by temperature and the content of THF; the oligomeric butadiene dilithium had better stability than the oligomeric isoprene dilithium. The by-reactions of non-inactivation had more serious effects on the average functionalities of the in(?). |
