What is Polyacrylonitrile?

Polyacrylonitrile is a synthetic polymer built from repeating acrylonitrile monomer units that link together into long, rigid chains. This chain structure gives the material a distinctive combination of high tensile strength, strong resistance to chemical attack, and stability under elevated temperatures. It is supplied as a solid and does not dissolve in water, but it readily dissolves in polar aprotic solvents such as DMF, DMSO, and N,N-dimethylacetamide, which is how it is typically processed into fibers and films.

Uses of Polyacrylonitrile

The largest single use of polyacrylonitrile is in fiber manufacturing, where it is spun into acrylic fiber prized for being soft to the touch, hard-wearing, and resistant to chemical exposure and outdoor weathering. These fibers end up in apparel, upholstery fabric, carpets, and heavy-duty industrial textiles.

Polyacrylonitrile also functions as the key precursor for manufacturing carbon fiber: the polymer is spun into fiber form and then further processed to yield the high-strength carbon fiber used in aerospace components, automotive parts, and construction reinforcement. Its film- and membrane-forming characteristics also make it useful in filtration systems, including membranes for water treatment, chemical processing separations, and gas separation equipment.

Safety Information

  • Store in a cool, dry, well-ventilated area in tightly closed containers, away from incompatible materials
  • Avoid contact with skin and eyes, and avoid inhaling dust generated during handling
  • Use appropriate PPE, including chemical-resistant gloves and protective clothing
  • No specific GHS hazard classification, H-statement codes, or storage class number were provided in the source data; refer to the current SDS for the applicable regulatory classification before use

FAQs: Polyacrylonitrile

Polyacrylonitrile is favored as a carbon fiber precursor because its polymer chains carry a high proportion of carbon and remain stable through the high-temperature processing steps needed for conversion.

No. It does dissolve in polar organic solvents such as DMF, DMSO, and N,N-dimethylacetamide, which is why these solvents are commonly used to process it into fibers, films, or membranes.

Polyacrylonitrile is supplied as a solid, and should be kept in tightly closed containers in a cool, dry, and well-ventilated storage area.

Acrylic fibers used in textiles are made from polyacrylonitrile, so the two are closely related but not identical in form — the raw polymer is processed and spun into fiber before becoming finished fabric.

Handlers should avoid skin/eye contact and inhalation of dust, and wear suitable gloves and protective clothing.
