Preparation method of water-soluble polymer dispersion

The invention relates to a preparation method of a water-soluble polymer dispersion. The water-soluble monomer is dispersed in a solution polymerization system containing a dispersant, an initiator and a metal ion scavenger to perform polymerization and obtain the water-soluble polymer dispersion, wherein the dispersant is a composite dispersant system and contains at least one kind of water-insoluble inorganic macroparticles and at least one water-soluble polymer dispersant. The invention utilizes the composite dispersant system in which the water-insoluble inorganic macroparticles are matched with the polymer dispersant to form dispersion coating mechanism so as to reduce the concentration of high molecular polymer in continuous phase and ensure that the rolling friction and rigid impact are mainly adopted between the polymer molecule chain and the macroparticles. Therefore, the viscosity of the dispersion is effectively reduced while the molecular weight of polyacrylamide polymer in the dispersion is not reduced, and the water-soluble polymer dispersion with high concentration, good solubility, uniform dispersion, high efficiency and full water-solubility can be prepared.
