CATIONIC POLYMER THICKENERS

摘要

Cationic polymer thickener consisting of a crosslinked water swellable cationic polymer containing at least one cationic monomer and optionally non-ionic and or anionic monomers wherein said polymer comprises less than 25% of water soluble polymeric chain by total weight of the polymer, and a cross-linking agent concentration of from 500 ppm to 5000 ppm relative to the polymer.
