COATED SUPERABSORBENT POLYMER PARTICLES AND PROCESSES THEREFORE |
| 摘要 |
Superabsorbent material, comprising first superabsorbent polymers, coated with second clay-crosslinked superabsorbent polymers, said second clay-crosslinked superabsorbent polymers being obtainable by the step of polymerization of a solution/dispersion of polymerizable compounds and clay particles, to obtain said second superabsorbent polymers, crosslinked by said clay particles, of a weight average largest particle dimension of less than 800 nm. |

1. A superabsorbent material, comprising: first superabsorbent polymers, coated with second clay-crosslinked superabsorbent polymers, said second clay-crosslinked superabsorbent polymers being polymerized in a solution or dispersion of polymerizable compounds, in the presence of a clay particle dispersion, crosslinked by said clay particles, said clay particles having a weight average largest particle dimension of less than 800 nm. |
