摘要/Abstract

摘要： 以N,N,N′,N′-四甲基乙二胺为配体合成了Zn-Fe氰化物配合物催化剂，以叔丁醇为链转移试剂，用正交试验方法探索了该催化剂开环聚合的最优条件，正交实验结果表明, 最佳反应条件为t=100 ℃, t=6 h, w(Cat)=15 mg, w(t-BuOH)=15 mg. 分析结果表明, 反应产物的数均分子量M_n为10000~13000，分子量分布较窄 (M_w/M_n≤1.30). 并对聚合反应机理进行了探讨.

Abstract: A new Fe-Zn double metal cyanide (DMC) complex is a very effective catalyst for the ringopening polymerization of propylene oxide. With tertbutyl alcohol as the chain transfer agent, orthogonal experimental design was used to find the optimal conditions for the polymerization. The optimal conditions: temperature 100 ℃,t=6 h,w(Cat)=15 mg,w(t-BuOH)=15 mg. Polyoxyproylene diols with M_n(10000～13000)were prepared, and these polymers exhibited the narrow polydispersity (M_w/M_n≤1.30). The me chanism of polymerizationwas discussed.

Key words: double metal cyanide complex, propylene oxide, orthogonal experimental design, ring-opening polymerization
