Abstract

A series of glycidyl azide polyol (GAP)-based ETPEs with different hard-segment contents were synthesized using GAP-diol, hexamethylene diisocyanate and 1, 4-butanediol as soft and hard segments, respectively, by prepolymerization. The synthesized GAP-based ETPEs were identified and characterized using Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and rheometric spectrometry. The results of FTIR showed the forming of carbonyl hydrogen bonds in ETPEs was affected by hard-segment contents of ETPEs. DSC results showed that the glass transition temperature (T g) of ETPEs was also affected by the percentage of hard-segment contents of ETPEs. It was shown by DMA and rheological measurements that the percentage of hard-segment contents of ETPE had a monotonic effect on the rheological properties of ETPEs.
