We present a study of the mechanical properties of porous polymer materials elaborated from the controlled formulation of emulsions and using a polyHIPE templating approach. This consists in the polymerization of high internal phase water-in-oil emulsions of controlled average size and dispersed phase volume fraction. We investigate the evolution of the linear and non-linearmechanical properties as a function of two sets of parameters, that define the structure (namely pore size and volumefraction) and the composition (chemical composition of the polymer walls) of the material.
