This paper focus on the modeling of thermo-chemo-mechanical behaviors for soft materials (polymer, rubber, ...) that can exhibit large strain in a rigorous thermodynamical framework. As an application it is considered the case of a thermo-viscoelastic material that can undergo chemical reactions which are described by a kinectic approach. Simple idealized and homogeneous numerical tests are considered and illustrate the availability of this framework to take into account reciprocal coupling between each physics.
