Analysis of the decomposition of an anhydride-cured epoxy resin by subcritical hydrolysis.

ABSTRACT: The decomposition of an anhydride-cured epoxy resin by subcritical hydrolysis is studied under variation of reaction temperature, decomposition duration and water volume using a batch reactor. Within the framework of a design of experiment, the process is evaluated by the gravimetric decomposition of the epoxy resin clearly showing that temperature is the most important factor. Duration and water volume have only smaller positive effects. The mass loss mechanism of the cube-shaped specimens corresponds to a heterogeneous surface degradation where material is only lost from the outer areas. The determination of glass transition temperatures after the experiments demonstrates that the water hardly affects the center of the epoxy cubes. Therefore, a core-shrinking model is successfully applie
