PURPOSE:To obtain titled polymer with high polymerization degree and water solubility, useful for significantly high-performance flocculant, by the polymerization of an acrylamide monomer in an aqueous medium in the presence of a specific aliphatic dialdehyde. CONSTITUTION:The objective polymer can be obtained by the polymerization, using as an initiator, a combination of a hydrogen peroxide aqueous solution and ferrous sulfate one, of an acrylamide monomer in an aqueous medium in the presence of an aliphatic dialdehyde of formula OHC-R-CHO (R is alkylene or alkenylene). Said dialdehyde is e.g., malonaldehyde, succinaldehyde, malealdehyde, fumaraldehyde, glutaraldehyde, adipaldehyde.
