'''Polyacrylonitrile''' ('''PAN''') is a [[resin]]ous, [[fiber|fibrous]], or [[rubber]]y organic [[polymer]]. Almost all polyacrylonitrile [[resin]]s are [[copolymer]]s made from mixtures of [[monomer]]s; with [[acrylonitrile]] as the main component. PAN fibers are the chemical [[wiktionary:Precursor|precursor]] of high-quality [[carbon fiber]]. It is chemically modified to make the carbon fibers found in [[tennis racket]]s, badminton rackets & high-tech [[bicycle]]s. It is a component [[repeat unit]] in several important [[copolymer]]s, such as [[styrene-acrylonitrile]] or SAN and [[ABS plastic]].
==Applications==
Homopolymers of polyacrylonitrile have been used as fibers in hot gas filtration systems, outdoor awnings, sails for yachts, and even fiber reinforced concrete. Mainly, copolymers containing polyacrylonitrile are used as fibers to make knitted clothing, like socks and sweaters, as well as outdoor products like tents and similar items. If the label of a piece of clothing says [[Acrylic fiber|"acrylic"]], then it is made out of some copolymer of polyacrylonitrile. It was made into spun fiber at DuPont in 1941 and marketed under the name of Orlon.[http://heritage.dupont.com/touchpoints/tp_1941/overview.shtml]
