This invention relates to the field of dispersant technology, and discloses a dispersant composition, its preparation method, and its application. The composition comprises the following components in parts by weight: 100 parts linear paraffin, 10-30 parts water, 20-40 parts dispersing material, 8-10 parts emulsifier, and 3-5 parts solubilizer, wherein the dispersing material is selected from bicarbonates and / or carbonates. The dispersant composition provided by this invention is non-toxic and biodegradable. When used in
polyacrylamide granulation, it results in
polyacrylamide products with high hydrolytic uniformity and rapid hydrophilic
solubility.
