An absorbent foam product prepared by mixing together a solid, particulate, water-insoluble, water-swellable polymer having a gel capacity of at least 10, a solid, particulate blowing agent, and a liquid polyhydroxy organic compound and allowing the mixture to foam. An absorbent article comprising a foam coated substrate, said foam coated substrate obtained by (a) mixing together a solid, particulate, water-insoluble, water-swellable polymer having a gel capacity of at least 10, a solid, particulate blowing agent, and a liquid polyhydroxy organic compound to obtain a foamable composition, (b) coating said composition onto a substrate, and (c) allowing the mixture to foam. A dual walled container for transporting aqueous fluids having a breakable inner wall and a non-breakable outer wall and having in a portion of the space between the two containers walls, a foam prepared by mixing together solid, particulate, water-insoluble, water-swellable polymer having a gel capacityy of at least 10, a solid, particulate blowing agent, and a liquid polyhydroxy organic compound and allowing the mixture to foam.
