Polyacrylonitrile powder is a polymer before spinning of polyacrylonitrile fiber.It is obtained by radical polymerization of monomeric acrylonitrile.The acrylonitrile units in the macromolecular chain are connected in a linker-tail manner.It is mainly used for making polyacrylonitrile fiber. Polyacrylonitrile fiber has the advantages of good weather resistance and solar resistance.It can maintain 77% of its original strength after 18 months of outdoor.It is also resistant to chemicals,especially inorganic acids,bleaching powders,hydrogen peroxide and general organic reagents
