摘要： 利用改进的5DXFT-IR光谱仪,测试了140℃下IPN聚合反应过程的红外发射光谱。利用峰面积比值法,计算了不同时间下的反应程度和动力学常数。实验结果表明:环氧树脂和聚氨酯反应均为一级反应,kepo=0.035,Kepo in IPN=0.10,Kpu=0.15。并讨论了反应与结构的关系。

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.
