A novel liquid crystalline (LC) epoxy monomer was cured with different types of hardeners. The thermal-degradation properties of cured thermosets were evaluated by thermogravimetric (TG) analysis. Several widely used kinetic models were reviewed and used to fit the TG data. The experimental results showed that the methods from one constant heating rate are insensitive to the magnitude of reaction order n. The Kissinger and Osawa methods from multiple processes would give more confident kinetic parameters in these observed systems. (C) 2000 John Wiley & Sons, Inc.
