Swelling of polyacrylamide gels in polyacrylamide solutions
Journal of Polymer Science Part B: Polymer Physics, 1998 Swelling behavior of polyacrylamide (PAAm) and polyacrylamide-co-poly- acrylic acid (PAAm-co-PAAc) gels was investigated in aqueous solutions of monodis- perse 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 the external solution increases.
