      abstract     = {Hypothesis: We synthesised monodisperse macroporous
                      polymers via polymerisation of water-in-monomer droplet
                      emulsions and obtained non-spherical pores with layered pore
                      walls. We hypothesise that this morphology is caused by
                      surfactant diffusion and phase separation during
                      polymerisation.Experiments: We varied the surfactant mass
                      fraction of the emulsions and polymerised the templates with
                      a water-soluble initiator. From the resulting macroporous
                      polymers we determined the shape of the pores and thickness
                      of the layers via scanning election microscopy. The response
                      of the monomer/surfactant mixture to polymerisation was
                      studied by a ternary phase diagram that simulated
                      polymerisation. Findings:The emergence of non-spherical
                      pores with layered pore walls is indeed caused by surfactant
                      diffusion and phase separation. During polymerisation the
                      surfactant molecules diffuse either to the water/monomer
                      interface or deeper into the continuous monomer phase. The
                      first process results in non-spherical pores, while the
                      second process generates layered pore walls.},
