| Abstract: | The FT-IR emission spectra(FT-IR EMS) of IPN during polymerizationunder 140℃ are measured using modified 5DX FT-IR spectrometer. The reactionextents and kinetic constants are calculated by peak-area ratio method. "The results show that both the polymerization of EPOand the formation of PUare firstorder reaction and kepo=0.035, kepo in IPN= 0.10, and kPU=0.15. The relation between reaction and structure is discussed. The results show that FT-IR EMSis an effective technique in the study of polymer reaction kinetic. |
