Applications
Potassium persulfate being a strong oxidant, has been very nicely employed used to initiate polymerization reactions, which can indeed found application in the polymer making industries for the synthesis of important polymers, beneficial in medicinal chemistry, or for commercial use.
Dosage and directions
Polymerisation:
Initiator for the emulsion or solution polymerisation of acrylic monomers, vinyl acetate, vinyl chloride etc. and for the emulsion copolymerisation of styrene, acrylonitrile, butadiene etc. Dosage: 0.1-0.5% KPS-5 (PPS). Temperature: 75-95°C. In combination with redox systems (ascorbic acid, Rongalit, sulfites or sugar - possibly in combination with heavy metal salts such as Fe2+ it can also be used for polymerisation reactions carried out at lower - and even at ambient - temperatures. To reduce the residual monomer content, a combination of KPS-5 (PPS) with TBHP-70-AQ is recommended, particularly in cases where redox systems are used.
Cosmetics: Essential component of bleaching formulations.
Paper: Modification of starch; Repulping particularly of wet-strength paper.
Textile: Desizing agent and bleach activator - particularly for cold bleaching (e.g. bleaching of Jeans).
Others:
- Chemical synthesis
- Water treatment (decontamination)
- Waste gas treatment; oxidative degradation of harmful substances (e.g. Hg)
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.
