Abstract Summary: Semi‐interpenetrating hydrogels (SIHs) of polyelectrolytes consisting of poly(acrylamide) hydrogel (PAAH) as matrix and sodium poly(styrenesulfonate) (NaPSS), poly(N,N′‐dimethyl‐N,N′‐diallylammonium chloride) (PDMDAAC), stoichiometric interpolyelectrolyte complex of NaPSS‐PDMDAAC, and linear polyethyleneimine‐metal complexes (PMC) as well as polymer‐protected palladium nanoparticles were prepared by in situ polymerization, e.g. crosslinked acrylamide chains were formed in aqueous solutions of NaPSS, PDMDAAC, NaPSS‐PDMDAAC (1:1 mol/mol), PMC and palladium nanoparticles protected by poly(N‐vinylpyrrolidone) (PVP), poly‐(vinyl alcohol) (PVA), poly(acrylic acid) (PAA), and linear poly(ethyleneimine) (LPEI) respectively in the presence of N,N′‐methylenebisacrylamide. For each system the equilibrium swelling degree α and the parameters n and k describing the mechanism of water transport into SIHs volume was determined. Catalytic properties of SIHs were studied in allyl alcohol hydrogenation and cyclohexane oxidation reactions.
