Abstract: Materials and a process are provided whereby polymers with the pendant group or end group containing —Si(OR?)3 (where R? is H, an alkyl group, Na, K, or NH4) are used to control aluminosilicate scaling in a nuclear waste process. When materials of the present invention are added to the nuclear waste liquor, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces. The present materials are effective at treatment concentrations that make them economically practical.

Abstract: Aqueous dispersions of anionic water-soluble or water-swellable polymers are provided, where the polymers have an anionic charge of greater than 16% and where the dispersions maintain their form at a pH of 5.1 or greater. Processes for making these dispersions are also disclosed, as well as methods of using these dispersions to treat water containing various types of suspended materials. Dry polymers, preferably formed by drying these aqueous dispersions, are also disclosed.

Abstract: Stable compositions as flocculants comprising a blend of at least two inverse emulsions, at least one of which is a polymeric microemulsion, provide effective flocculating performance over time. Methods for preparing stable emulsion blends use stabilizing amounts of aldehyde scavenger.

Abstract: A microporous membrane modified by coating or grafting thereon a polyionene material. The thus-modified microporous membrane is useful for separating microorganism-originated contaminants from biological liquids.

Abstract: Polyionene-transformed modified polymer-polysaccharide separation matrix and use thereof in removing contaminants of microorganism origin from biological liquids are disclosed.
