To elucidate the interaction between VE and MEPECO along with the curing agents, spectral analysis from ATR-FTIR under dry air at ambient temperature was used. The IR spectra were recorded on a JASCO (FT-IR-6300, FTIR spectrometer, United Kingdom). The percentage of transmittance spectra was collected with 32 scans at a resolution of 4 cm1 in the 4000 to 400 cm1 range.
