Rotational molding is a new process for thermosets, few research works have been done on this subject. The goal of this study is to determine the optimal conditions (time, temperature, viscosity, etc) of this process for an epoxy‐amine system. The thermal and rheological analysis help us to investigate the vitrification and the gelation of the reactive system (DGEBA‐DETDA) and to draw the TTT diagram. We have completed this diagram by adding the isoviscosity curves to determine the available domain for rotational molding. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
