Abstract
FIELD: preparation of poly- N, N- dimethylaminoethyl methacrylate dihydrosulfate as flocculant for dehydration of sewage sediments. SUBSTANCE: invention makes it possible to obtain polymer having increased (15-25)•10molecular weight and high flocculating activity (effectiveness is increased by 49- 52 %). Effect is achieved by using redox system during monomer polymerization, said redox system comprising cobalt sulfate, amine acid, sorvitol or glucose at 0.3- 0.9: 3.0-9.0:1.5-9.0 equivalent ratio, respectively, and polymerization is carried out at pH 1.2-3.5 and monomer concentration of 36.4-65.6 wt % in aqueous solution. EFFECT: improved properties of the title compound and more efficient preparation process. 3 cl, 1 tbl
