MICROPOROUS POLYMER MEMBRANE MODIFIED BY WATER-SOLUBLE POLYMER, METHODS OF ITS PRODUCTION AND APPLICATION Russian patent published in 2012 - IPC B01D71/26 C08J7/04 C08L23/00 H01M2/16 H01G9/02

Abstract RU 2470700 C2

FIELD: process engineering.

SUBSTANCE: invention relates to cellular materials. Microporous olefin membrane modified by water-soluble polymer is produced by copolymerisation of the mix composed of 100 parts of water-soluble polymer, 30-500 parts of hydrophobia monomer, 0-200 parts of hydrophilic monomer and 1-5 parts of initiator to make colloidal polymer emulsion. 0-100% of inorganic filler and 20-100% of plasticiser are added to emulsion, at 100%-content of dry substance in said emulsion, to make suspension. Suspension is applied on one or two surfaces of said membrane and dried.

EFFECT: heat-resistant membrane with low heat setting.
