Aqueous Salt Absorption by Ampholytic Polysaccharides.
Abstract
Studies of the solution properties of polyampholytes have revealed that these polymers are capable of undergoing viscosity increases in the presence of increasing salt concentration. Employing this unique characteristic, we have prepared graft copolymers of the ampholytic ion pair comonomer 3-methacrylamidopropyltrimethylammonium 2-acrylamido-2-methylpropanesulfonate with acrylamide onto starch and hydroxyethyl cellulose by both ceric ion and cobalt-60 irradiation. The deionized water and aqueous salt absorbing properties of these materials are reported. Originator supplied keywords include: starch; hydroxyethyl cellulose; graft copolymers; solution properties; salt absorption; ampholytic polysaccharides; polyampholytes.
