The invention relates to a kind of cation water-soluble macromolecule dispersoid. It includes inorganic salt watery solution, more than one kind of cation addition polymer soluble in the inorganic salt watery solution and more than one kind of water-soluble cation monomer and methylol acrylamide or acrylamide monomer to form water-soluble monomer system. Because the invention uses the compound dispersing agent comprised of cation addition polymer and condensation polymer dispersing agent, it makes the technology effect of cation water-soluble macromolecule dispersoid very remarkable. Compared with the cation addition polymer, the condensation polymer dispersing agent has lower molecular weight and bigger stoichiometic concentration; it's easy to absorb and compactly cover on the surface of particles, and stabilize the dispersed particles by using the repellent effect of its charges; it form microphase separation state between the separated particles and the dissolution state macromolecules, to have the effect of stabilizing the dispersing system.
