Gelation of Hydrophilic Polymer Bearing Metal-coordination Unit with Various Metal Ions

Abstract Gelation of a hydrophilic polymer bearing a metal-coordination unit with various metal ions was examined. Gels with different morphologies were formed depending on the metal ion species. The formation mechanism for these gels could be explained based on their cross-linking rates. Gelation in two-component solutions containing different ratios of PdII to other metal ions (AuIII and PtIV) was also investigated.
