ABSTRACT:
Disclosed are methods of producing supported organic catalyst systems which find particular use in polymerization reactions. The methods comprise generally, the steps of (a) providing an organic catalyst solution comprising an organic catalyst dissolved in a solvent; (b) contacting the organic catalyst solution with a solid support material; and (c) removing the solvent from the support material by using one or more supercritical-like solvents.
