    Abstract

    Polyurethane (PU) foam-layered silicate nanocomposites were formed via reaction of polyol/water/sodium montmorillonite (Na-MMT) mixtures with toluene diisocyanate (TDI). The kinetics of both the PU copolymerisation and the microphase separation between poly(ether-urethane) soft segments and polyurea hard segments were determined using forced-adiabatic, attenuated total reflectance FTIR spectroscopy. Real-time chemorheological measurements under forced-adiabatic conditions were used to give modulus development and changes in normal force during the formation of reacting foams. Increasing silicate content accelerates polymerisation and decreases the time for microphase separation between soft and hard segments within PU foam nanocomposites.
