Abstract

A low density, open cell polymeric body is formed by coating or filling a reticulated polymeric foam with a liquid-form polymer which is resistant to high temperatures, curing the liquid form polymer in and on the foam and then removing the foam skeleton by dissolving and leaching the foam out of the solid polymeric body which remains.
