POLY(DIALKYLAMINOALKYL (METH)ACRYLAMIDE)-BASED SUPERABSORBENT GELS |
| 摘要 |
Poly(dialkylaminoalkyl (meth)acrylamide)-based superabsorbent gels are disclosed. The superabsorbent gels either comprise a mixture of a poly(dialkylaminoalkyl (meth)acrylamide) polymer and an acidic water-absorbing polymer, like polyacrylic acid, or comprise a salt of a poly(dialkylaminoalkyl (meth)acrylamide) polymer. An improved method of preparing an N-(dialkylaminoalkyl) (meth)acrylamide monomer also is disclosed. |
