The work of the all-union scientific research institute for man-made fibers in the field of ion-exchange fibers

Preparation, characterization, and properties of polyacrylonitrile–silica gel anion exchange composite fibers

“…Some fibrous anion exchangers were synthesized on the basis of industrially produced PAN fiber [11–18]. These materials are industrially produced under trade mark FIBAN [13], VION [12, 18], and NITRON [19].…”

“…Some fibrous anion exchangers were synthesized on the basis of industrially produced PAN fiber [11–18]. These materials are industrially produced under trade mark FIBAN [13], VION [12, 18], and NITRON [19]. There are numerous reports on polymeric organic–inorganic fibrous cation exchange composite materials [20–22], but little work has been done on the synthesis and applications of polymeric organic–inorganic fibrous anion exchange composite material.…”

Acid–base properties of ion exchangers. III. Anion exchangers on the basis of polyacrylonitrile fiber

“…[1][2][3][4][5][6][7][8][9]. These materials are industrially produced under trademarks FIBAN [6] and VION [4,10]. Several varieties of ion exchangers of this type containing weak base amino groups and carboxylic acid groups have found an application in air purification from acid gases [11,12].…”
