The microporous (gel‐type) functional resin co‐poly‐ N , N ‐dimethylacrylamide (DMAA) (88 % mol)/methacrylic acid (MAA) (8 % mol)/ N , N ′‐methylenebisacrylamide (MBAA) (4 % mol) (MPIF(H)) is employed as the hosting framework for the production of resin‐supported Pd 0 nanoclusters. The obtained composite MPIF − Na + /Pd 0 is prepared upon reducing, in ethanol, MPIF − Pd 2+ 0.5 , obtained upon previous homogeneous dispersion of “Pd 2+ ” inside the resin particles (XRMA control) through ion‐exchange. Metal nanoclusters appear to be size‐controlled (2.0±0.2 nm) and are seen to reasonably fit the predominant resin “nanopores” diameter, determined in ethanol (3.2 nm) by means of inverse steric exclusion chromatography (ISEC).
