METHOD TO PRODUCE HIGH-POROSITY POLYMER MATERIAL Russian patent published in 2009 - IPC C22C1/08 C08J9/26 

FIELD: process engineering.

SUBSTANCE: invention relates to process engineering and can be used for producing high-porosity materials made from non-metal inorganic powder suitable in operation as filters of gas, solvents, catalyst carriers and heat insulation agents. In compliance with this method, porous matrix with a system of intercommunicated open pores is produced from granules of low-melting water-insoluble, or readily-sublimated or water-soluble organic substances, or ice. Pores are filled with fluid mass that does not dissolve aforesaid matrix and represents conducting or not-conducting mix of polymers, mix of polymer powder with polymer binder, suspension or polymer solution with water or organic fluid. Matrix is removed to produce preset shape- and size-pores in its place. Matrix removed, obtained material is consolidated.

EFFECT: production of preset shape- and size pores, simplified process.
