The thermal decomposition of complexes produced from bentonite and a linear polyacrylamide (PAM) was investigated by using thermogravimetry-mass spectrometry (TG-MS). Data obtained for the polymer degradation supported the model proposed by Leung et al. Thermal behaviour of bentonite-PAM complexes was mainly determined by PAM degradation below 580°C. Above this temperature decomposition of bentonite proved to be the decisive process. Measurements revealed the formation of strong bonding between the constituents of the complexes.
