Abstract:
1. A polymer incarcerated Lewis acid metal catalyst comprising a Lewis acid metal incarcerated in a crosslinked polymer, wherein the crosslinked polymer is obtained by crosslinking a crosslinkable polymer which has hydrophilic substituents containing crosslinking groups linked directly to the crosslinkable polymer main chain and hydrophobic substituents linked directly to the crosslinkable polymer main chain, wherein the hydrophobic substituents do not contain hydrophilic groups or crosslinking groups, and further wherein the crosslinkable polymer contains at least one type of monomer unit containing (a) an aromatic hydrophobic substituent which does not contain hydrophilic groups or crosslinking groups and (b) a hydrophilic substituent containing a crosslinking group.
