The ability of linear stiff-chain poly(sodium p-phenylenesulfonate) to self-assemble in aqueous media with the formation of rodlike aggregates was used to immobilize it in a polyacrylamide network without covalent bonding. It was shown that polyelectrolyte rods impart simultaneously two useful properties to the gel: higher ability to absorb water and higher mechanical strength. The counterions of charged rods ensure the enhancement of the absorption capacity of the gel, while stiff elements strengthen the gel. This makes such systems potentially promising as superabsorbent materials.
