Abstract
A method of producing a form-stable sintered porous shaped phenolic resin article with continuous open pore structure and high macroporosity, in which a phenolic resin mixture is partially cured to a solid which is then comminuted to give a comminuted resin. The comminuted resin is admixed with water, hexamethylene tetramine and a cellulose ether, and the resulting comminuted resin mixture is formed into a shaped article which is allowed to come to equilibrium with air having a relative humidity of less than 100% at a temperature below 100.degree. C. The shaped article is then sintered to produce a form-stable sintered porous product.
