The swelling behaviour and elastic properties of gelatin gels are reported. Ampholytic swelling properties have been investigated. Antipolyelectrolyte performance is observed when gels are swollen in di β erent salt solutions. Swelling behaviour in high salt solutions is di β erent from that in low sa

Swelling behavior of polyacrylamide (PAAm) and polyacrylamide-co-polyacrylic acid (PAAm-co-PAAc) gels was investigated in aqueous solutions of monodisperse PAAms with molecular weights ( M V w ) ranging from 1.5 1 10 3 to 5 1 10 6 g/mol. The volume of the gels decreases as the PAAm concentration in
## Spontaneous vesicle formation was observed in aqueous mixtures of partially hydrolyzed polyacrylamide and single-tailed cationic surfactants. The influences of pH, addition of long-chain alcohols, variation of hydrocarbon chain length, and head group size of the cationic surfactants were invest
