CHARACTERIZATION OF CATALYSTS SUPPORTED O N POLYMERS

A review concerns characterization of the catalysts based on polymers and compares them with inorganic catalysts. Characterization of microp orous polymer catalysts exploited in liquid-phase systems is mainly di scussed. Special attention is paid to the combination of methods for t he description of mobilities molecules inside the polymer, e.g., to th e evaluation of ''nanoscopic'' morphology from ISEC data, rotational m obility calculated from EPR measurements of a probe confined in the sw ollen polymer, and self-diffusion coefficients estimated from spin-ech o NMR with a steady-state gradient of the superposed magnetic field. T he consistency of obtained quantities with the catalytic activity is a lso discussed.
