KINETIC STUDIES ON COORDINATION POLYMERIZATION OF BUTADIENE VIA REAL-TIME ART-FTIR MONITORING
原位ATR-FTIR法研究丁二烯配位聚合反应动力学

FTIR spectroscopy in combination with a diamond tipped attenuated total reflectance(ATR) immersion probe was utilized to study in situ coordination polymerization of butadiene(Bd) in hexane(HEX) with Neodymium-based catalyst.The relationship of their intensity at signal bands of Bd and its concentration were investigated.The kinetic studies of polymerization of Bd were conducted by in situ ATR-FTIR.The signal band at 1592 cm~(-1) was assigned to the stretching vibration of Bd,and the signal bands at 1010 cm...
