The influence of the lixiviates originated in a municipal landfill on the thermal degradation of a polymeric system composed of a diglycidyl ether of bisphenol A ( n = 0) and 1,2‐diaminecyclohexane was studied by dynamic mechanical analysis. Storage modulus ( E ′), loss modulus ( E ″), and glass transition temperature were measured to make a comparative study between the samples before and after being exposed to the chemical compounds in the lixiviate agents. The different data obtained were analyzed to check the resistance of these materials to chemical attack and the possibility of their use as coating materials in plants where those reagents were present. Thermal stability of the system diglycidyl ether of bisphenol A/1,2‐diaminecyclohexane exposed to the attack of lixiviates has also been studied by thermogravimetric analysis. A quantitative study of the gases originated during thermal degradation of the epoxy/diamine system made by infrared spectroscopy. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 72: 443–453, 1999
