Cationic PVOH K Series


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

Structural formula

Structural formula K series

  • ・Its aqueous solution selectively adsorbs negatively charged matters (natural fiber, pulp, etc.).
  • ・Excellent emulsifier and dispersant behavior due to its surface activity and protective colloid properties. Resulting emulsions have selective adsorption properties as well.
  • ・Its aqueous solution behaves as a polymer electrolyte, and forms an ion complex and anionic water-soluble resin.
