摘要
在催化剂的存在下,使MDI进行等温聚合,采用FTIR快速红外光谱技术跟踪2270cm^(-1)处峰的变化,以此来研究MDI生成聚异氰脲酸酯的等温反应动力学,以及温度、催化剂浓度等对反应速度的影响.
MDI was isothermally polymerized in the presence of catalyst and the isothermic reaction kinetics was studied by FTIR, in which the changing at 2270-1(-NCO) was followed. The effect of temperature and catalyst content on the reaction -rate was also studied.
