High water-absorbent copolymers comprising acrylic acid (AA) and acrylamide (AM) were prepared in the presence of a crosslinking agent, monofunctional aldehyde, by a solution polymerization technique using a redox initiation system. Such copolymers have very high water absorbency and absorbing kinet
The sedimentation rate of ochre suspension in the presence of copolymer decreases with increase of ionic strength (p) and decrease of copolymer concentration. The dependence of the flocculation properties of copolymers for ochre on chemical inhomogeneity of the copolymers is more significant for low
