Ammonium persulfate is a white,crystalline,odourless salt.It isused as initiator for the polymerisation of monomers and as astrong oxidizing agent in many application.It has the particularadvantage of being almost nonhygroscopic,of having a particularlygood storage stability as a result of its extremely high purity andof being easy and safe to handle.

APS is a suitable initiator for the emulsion or solutionpolymerisation of acrylic monomers,vinyl acetate,vinyl chlorideetc.and for the emulsion copolymerisation ofstyrence,acrylonitrile,butadiene etc..APS is also a kind ofoxidizing 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 coatingmaterials.
(4) Desizing agent and bleach activator.
(5) An essential component of bleaching formulation for haircosmetics.
