Abstract Thermal stability of methacrylamide intercalated octadecylammonium montmorillonite (OD-M/MA) is limited by rapid desorption of methacrylamide (MA) at 140°C. It was improved by γ-irradiation. The irradiation intercalation complex OD-M/MA γ shows significant shift of the whole desorption process towards higher temperatures. However, part of the adsorbed organic material is released at 50°C signalizing presence of some volatile fractions. Decomposition products of the intercalated material and long-chain alkylamides in the acetone extract indicate complex reactions between MA and octadecylammonium chains. An additional swelling of the silicate structure occurs after γ-ray initiation and is probably related to the reaction products with a certain degree of cross-linking in the interlayers.
