Abstract

Based on the principle of click chemistry, azido-terminated tetrahydrofuran/ethylene oxide copolyether (N₃PET4000) was synthesized via 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 N₃PET 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 N₃PET4000 curing system has better mechanical properties. Crosslinking network generated the highest cross-linking density when R value is about 1.1.
