A relatively soft procedure was proposed for the preparation of tough and fast responsive ionic P(DMAEMA-co-AMPS) cryogels in which the tertiary amine containing monomer imparts pH-sensitivity and the ionic comonomer AMPS introduces the ionic moiety. The equilibrium swelling behavior as well as the elasticity of ionic P(DMAEMA-co-AMPS) cryogels were investigated and the effective diffusion coefficient of water was estimated.
