POLYACRYLAMIDE-BASED COMPOSITION (VARIANTS) Russian patent published in 2007 - IPC C08L33/26 C08K5/05 C08K9/04 B01D37/03 B01D21/00 B01D51/02 B03D3/06 C02F1/56

Abstract RU 2291169 C2

FIELD: polymer materials.

SUBSTANCE: invention relates to polyacrylamide flocculants possessing elevated storage stability. The latter property is achieved by using, as stabilizing agents, organic low-molecular weight aliphatic-series chlorohydrins, in particular ethylenechlorohydrin and propylenechlorohydrin. Composition comprises: 0.5% polyacrylamide, 0.2-0.3% ethylenechlorohydrin or 0.15-0.3% propylenechlorohydrin, and water - the balance.

EFFECT: increased storage time of polyacrylamide solutions from 2 to 180 days.
