POLYELECTROLYTE COMPLEXES AS THICKENERS FOR HIGH IONIC STRENGTH SALT SOLUTIONS |
摘要 |
A polyelectrolyte complex composition capable of viscosifying or thickening an aqueous high salt-containing system comprises a mixture of at least one anionic polymer and at least one cationic polymer in an inorganic salt-containing aqueous medium. The anionic polymer and cationic polymer can each be linear and water-soluble, crosslinked and water-soluble, or crosslinked and water-insoluble or swellable. |
