METHOD OF PREPARING CATION-ACTIVE FLOCCULANT Russian patent published in 1997 - IPC

Abstract RU 2079443 C1

FIELD: reagents for waste water purification. SUBSTANCE: invention concerns preparing cation-active flocculant intended to be used for cleaning waste water from suspended materials, anion-active surfactants, petroleum derivatives, and other organic impurities, and also for dehydration of sediments. Method includes alkylation with halogenorganic compounds of polymerized 2-methyl-2-vinylpyridine. The latter is first subjected to water-emulsion polymerization and resultant latex having molecular weight 100-300 thousand is treated at 45-65 C with benzyl chloride in presence of stabilizing additive such as polymeric quaternary ammonium base in amount 6-8 weight parts per 100 weight parts of latex. EFFECT: improved synthetic procedure. 4 tbl
