  Ammonium persulfate is a white,crystalline,odourless salt.It is used as initiator for the polymerisation of monomers and as a strong oxidizing agent in many application.It has the particular advantage of being almost nonhygroscopic,of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.
  APS is a suitable initiator for the emulsion or solution polymerisation of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion copolymerisation of styrence,acrylonitrile,butadiene etc..APS is also a kind of oxidizing agent:
  (1) Used in cleaning and pickling of metal surfaces.
  (2) Used in accelerated curing of low formaldehyde adhesives.
  (3)Used in modification of starch,production of binders and coating materials.
  (4) Desizing agent and bleach activator.
  (5) An essential component of bleaching formulation for hair cosmetics.
