Cationic PVOH K Series


A modified PVOH having a cationic group (quaternary ammonium salt) on its side chain.

Structural formula

Structural formula K series

  • Gohsenx™ K shows selective adsorption to negative charged materials (natural fiber, pulp, etc.)
  • Gohsenx™ K shows excellent emulsifier and dispersing behavior due to its surface activity and protective colloid properties. Resulting emulsions have also selective adsorption properties as well.
  • Gohsenx™ K solution behaves as a polymer electrolyte and forms an ion complex with anionic water soluble resin.
