✦ Synopsis

Condensation of aromatic aldehydes with nitromethane or fluorene in the presence of polymer-bound crown ethers complexed with alkali metal or ammonium salts and hydroxides was used to study the kinetics of these catalytic reactions. The course of the reactions was found to depend on the properties of the polymeric matrix used, the rate of condensation being affected by the sorption of substrates and reaction products and by the swelling capacity of the matrix.
