摘要
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 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 N3PET4000 curing system has better mechanical properties. Crosslinking network generated the highest cross-linking density when R value is about 1.1.关键词
