Cationic PVOH
GOHSEFIMER K
A modified PVOH having a cationic group (quaternary ammonium salt) on its side chain.
- Properties
-
- ・Its excellent membrane forming capability allows a resilient, transparent membrane to be formed.
- ・Its aqueous solution selectively adsorbs negatively charged matter (natural fiber, pulp, etc.).
- ・Excellent emulsifier and dispersant behaviour due to surface activity and protective colloid properties. Resulting emulsions will have selective adsorption properties.
- ・Its aqueous solution behaves as a polymer electrolyte, and forms an ion complex in conjunction with an anionic water-soluble resin.
