A method for solution polymerization. The method comprises polymerizing in a solvent a monomer mixture comprising: (a) 5 to 95 wt % of a C-Cethylenically unsaturated dicarboxylic acid; and (b) 5 to 95 wt % of vinyl acetate; wherein the solvent comprises 51 to 88 wt % isopropanol and 12 to 49 wt % water.

Solution polymerization in isopropanol and water

Provided are compositions and methods that are useful for clarifying water, reducing turbidity of water, and removing salts from water. The compositions comprise (a) an anionic flocculant comprising at least one of an alkali swellable emulsion (ASE) or hydrophobically-modified alkali swellable emulsion (HASE), and (b) a cationic flocculant comprising (i) an aluminum-containing compound, and (ii) a copolymer of acrylamide and a cationic monomer comprising at least one of a diallyldialkylammonium quaternary compound, acrylamidoalkyltrialkylammonium quaternary compound, methacrylamidoalkyltrialkylammonium quaternary compound, and mixtures thereof.

Water treatment compositions and methods of use

Disclosed are a process and an apparatus for using an olefin as an azeotropic entrainer to isolate a target organic compound from a waste stream. The olefin may be, for example, 1-decene, 1-dodecene, or 1-tetradecene. The target organic compound may be 1,3-dichloro-2-propanol in waste stream comprising a 2,2'-oxybis(1-chloropropane).
