Summary The pore structures of Amberlyst A-21 and of a polystyrene support which is cross linked with 5.6% divinylbenzene2, were investigated using the scanning electron microscope. Both polymers were found to possess a granularly structured surface. However, in Amberlyst A-21 a distinct pore structure is observed in the interior which is not found in the polystyrene support cross linked with 5.6% divinylbenzene. Accordingly Amberlyst A-21 might be macroporous while the other support, which was investigated, appears to be rather a modified type of normally cross linked polystyrene.
