摘要：

The routine application of simultaneous thermogravimetry-mass spectrometry (TG-MS) in the analysis of liquid crystalline polymers is discussed. Isothermal and dynamical analyses have been carried out in an inert atmosphere. The TG-MS interface was modified to overcome condensation and memory effects. A low cost, high performance quadrupole mass spectrometer in a TG-MS coupling allows identification of the volatile decomposition products (weight loss), providing both quantitative and qualitative information about the evolved gases, with temporal resolution between the two analytical procedures.
