Thermal degradation and combustion processes of commercial liquid crystalline polyesters (LCPs) were studied by directly coupled thermal analysis-mass spectrometry (TA-MS) under inert and quasi-air atmosphere. The first major degradation step of LCPs was the ester linkage rupture reaction. In the case of fully aromatic LCPs, this process was little influenced by 20% oxygen atmosphere. The main evolved gaseous products at this step were CO, CO2, H2O and phenol for fully aromatic LCP samples, in addition, aliphatic products for a semi-aromatic LCP sample. Evolution of CO2 was followed by that of flammable organic products for fully aromatic LCPs, while flammable organic products evolved prior to CO2 for semi-aromatic LCP. The flame resistant and self-extinguishing mechanisms of LCPs are discussed on the basis of their thermal degradation behavior.
