Abstract (en)
[origin: WO9932543A1] An alkenyl aromatic/unsaturated nitrile/conjugated diene microcellular foam, exemplified in a styrene/acrylonitrile/butadiene foam, has a void volume of at least about 50 % and a relative toughness of at least about 500 psi. The high toughness is achieved with little or no reinforcing agent. The foam is blown without chemical blowing agent and is highly thermoformable.
