ABSTRACT:
A method for making reticulated foam structure of a crosslinkable thermosetting polymer which includes the steps of dissolving the polymer in a relatively volatile solvent, forming the resultant solution into an emulsion with a relatively less volatile emulsifying vehicle, forming the emulsion into the desired structure, removing the solvent from the structure, removing the vehicle and curing the structure to form a reticulated foam structure.
