  • What is Polysulphide Sealant – Uses and Benefits - Painter Doug

    Polysulfides are a type of chemical compound that is made up of chains of sulfur atoms. It is a class of polymers that are composed of many sulfur atoms and hydrocarbons and can be synthesized using condensation. If you place polysulfides in water, you'll notice quickly that it is insoluble, like many other organic fluids and substances.

  • Polysulfide - an overview | ScienceDirect Topics

    Polysulfide pulping is a variant of kraft pulping in which half or more of the sodium sulfide of kraft white liquor is first oxidized. This orange liquor has the ability to preferentially oxidize end groups of hemicelluloses, making them more stable to alkaline attack and resulting in higher yields of pulp from wood.
