    Abstract: The thermal degradation behaviour of epoxy/unsaturated polyester based polymer interpenetrating networks (IPNs), and
    unsaturated polyester containing various flame-retardants have been investigated by TGA and Py/GC/MS. The kinetic parameters
    of various polymers were analysed by conventional and modulated thermogravimetric analysis (MTGA) methods. The activation
    energies of degradation were calculated by the CoatseRedfern and MTGA methods, respectively. The results of both conventional
    and MTGA analyses reveal that the decomposition of IPNs consists of two non-interfering decomposition processes for epoxy
    polymer and cured unsaturated polyester, respectively. For the flame-retardant containing unsaturated polyesters, ammonium
    polyphosphate (APP) played an important role in the second-step of the pyrolysis reaction of APP-containing samples. It is
    important to note that the possibilities of reaction order for these pyrolysis processes are significantly distinguishable by Coatse
    Redfern method. Furthermore, the activation energies for various samples calculated by MTGA method are on average larger than
    those calculated from the CoatseRedfern method. The results also reveal that when either the flame-retardant or the epoxy was
    added to the unsaturated polyester, the heat resistance of the unsaturated polyester was enhanced.
