Abstract
A method is shown for making porous thermoresin structures. By the method, the thermoresin is at least partially solvated, formed into a desired shape, and cooled until droplets of the solvent form by syneresis within the shape. Further cooling crystalizes the droplets. These crystalized droplets are subsequently removed to leave a porous structure.
