NANOGELS FOR DELAYED GELATION |
| 摘要 |
The instant application relates to nanogels or compositions that hold multivalent metal ions until some level of nanogel degradation has occurred, then slowly release the multivalent metal ions for gelation with carboxylate containing polymers. Compositions comprising such nanogels, together with polymers that can be crosslinked with multivalent metal ions, allow the deployment of such mixtures in various applications, and greatly increased gelation times. |

1. A degradable composition comprising a polymer having releasable carboxylate groups complexed with a multivalent metal ion, said degradable composition lasting at least 5 days at 85° C. in a brine solution having 23 g/l NaCl, and thereafter degrading and releasing said multivalent metal ion. |
