Effect of organophilized montmorillonite (MMT) on structure formed by reactively induced phase separation (RIPS) and related properties of epoxy containing 5-30% polycaprolactone (PCL) were studied. The effect of clay is significant especially with supercritical PCL concentration, the radical change in morphology with 15% and 20% PCL leads to substantial improvement of mechanical behaviour. The main reason is change in epoxy phase parameters by clay, supporting its continuity. The mechanical behaviour is further influenced by change in coexisting phases composition due to reduced degree of phase separation caused by clay. The results indicate the potential of clay to tailor structure and properties of RIPS system with significant dynamic asymmetry of components.
