Polymerization
Initiator for the emulsion or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride etc. and for the emulsion copolymerization of stirene, acrylonitrile, butadiene etc.- Dosage: 0.1 - 0.5 % KPS (PPS)
- Temperature: 75 - 95 °C.
In combination with redox systems (ascorbic acid, Rongalite, sulfites or sugar possibly in combination with heavy metal salts such as Fe2+) it can also be used for polymerization reactions carried out at lower and even at ambient temperatures. To reduce the residual monomer content, a combination of KPS (PPS) with TBHP-70-AQ is recommended, particularly in cases where redox systems are used.
Cosemtics
- 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)
Properties
- Physical Form
- Appearance
- White, finely crystalline solid
