摘要
依据点击化学反应原理,以端羟基环氧乙烷-四氢呋喃共聚醚(PET4000)和NaN3为原料经叠氮化反应得到端叠氮基环氧乙烷-四氢呋喃共聚醚(N3PET4000)。用FTIR、NMR、GPC对N3PET4000进行了表征。研究了N3PET4000与多炔化合物的固化反应,对不同R值的胶片力学性能进行了表征。结果表明,R值为1.0时,N3PET4000固化体系具有良好的力学性能;R值为1.1左右时形成的交联网络的交联密度最大。
Based on the principle of click chemistry, azido-terminated tetrahydrofuran/ethylene oxide copolyether （N3 PET4000） was synthesized yia using tetrahydrofuran/ethylene oxide copolyether （PET4000） and NaN3 as starting materials. N3PET4000 was characterized by fourier transform infrared （FTIR） , nuclear magnetic resonance （NMR）, gel permeation chromatography （GPC） and elemental analysis. The solidification reaction between N3 PET 4000 and multi acetylene compound was studied. The mechanical properties of N3PET4000 film with different values of R were characterized. When the R value is 1.0, the N3 PET4000 curing system has better mechanical properties. Crosslinking network generated the highest cross-linking density when R value is about 1.1.
