Frequently Asked Questions
It is most commonly abbreviated as PAN.
It is entirely synthetic, produced through the polymerisation of acrylonitrile monomer.
Its main application is as the primary precursor material in the production of high-performance carbon fibres.
Not directly. While its related fibres (acrylic, modacrylic) are used in clothing, pure polyacrylonitrile is an industrial material processed further into carbon fibre or specialised textiles.
A synthetic, thermoplastic polymer made from the monomer acrylonitrile, used chiefly to create acrylic and modacrylic fibres.
Polyacrylonitrile is usually technical, scientific in register.
Polyacrylonitrile: in British English it is pronounced /ˌpɒl.i.æk.rɪ.ləʊˈnaɪ.traɪl/, and in American English it is pronounced /ˌpɑː.li.æk.rɪ.loʊˈnaɪ.traɪl/. Tap the audio buttons above to hear it.
