Polyacrylonitrile (PAN) or Orlon.

Orlon is a polymer of vinyl cyanide (acrylonitrile).
It is obtained by addition polymerisation of acrylonitrile in the presence of a peroxide catalyst.

Polyacrylonitrile
It appears as a white solid.
Polyacrylonitrile is insoluble in water.
It is very inert and resistant to most organic solvents and acids.
It is UV resistant.
Its fibers are resistant to breaking, are soft, comfortable and thermal insulation.
It is used as fibres to make knitted clothes like socks, sweaters etc.
It is also used as fibre reinforced concrete, sails for yachts etc.
Polyacrylonitrile is usually used to make other polymers like carbon fibres.
It is also used as fibres for outdoor awnings. Next
