摘要

Kinetics of polymerization of 4,4'-bismalemidodiphenyl methane (BMI) were studied in the temperature range of 158-222 degrees C by inverse gas chromatography (IGC) technique. BMI was synthesized and purified and then coated on DMCS treated chromosorb for preparation of GC column. Retention behavior of dimethyl formamide was studied at different temperatures and at different time intervals to follow the phase changes and kinetics of polymerization, respectively. The kinetic data obtained by IGC were compared with those obtained by differential scanning calorimetry. (C) 1997 John Wiley & Sons, Inc. [References: 12]
