Graft polysaccharides and their use as sequestering agents |
| 摘要 |
Graft polysaccharides comprising a polymer backbone consisting essentially of a polydextrose having an average-weight molecular mass of less than 10,000 and grafts grafted thereon derived from a water-soluble ethylenically unsaturated monomer. The graft polysaccharides are useful as sequestering agents for alkaline-earth metal ions.
