METHOD FOR OBTAINING NANOPOROUS POLYMER MATERIALS Russian patent published in 2016 - IPC C08J9/28 B82B1/00 B29C55/00 B29C55/02 C08J5/18 D06M13/00 

FIELD: chemistry.

SUBSTANCE: method includes single-axis extension of polymer product of prolonged shape in liquid medium with its following removal from product volume under conditions of product holding in tense condition in direction of extension. As liquid medium applied is bi-component direct water emulsion of oil-in-water type based on solvents, which are physically active liquid mediums with respect to polymer and which do not mix with water at temperature of extension, forming disperse medium, and water is prolonged phase. Quantity of emulsified liquid medium in water must be less than 2 vol %. As polymer product of prolonged shape any object, selected from the group: film, fibre, ribbon, tube, rod, can be applied.

EFFECT: simplification of method for obtaining nanoporous polymer materials with open pores, considerable reduction its cost due to reduced consumption of expensive and ecologically dangerous reagents, elimination of its fire-hazard and improvement of ecological indices of method with preservation of high values of parameters of volume porosity of obtained polymers.
