摘要： The present disclosure relates to a preparation method of a super absorbent polymer capable of preparing a super absorbent polymer exhibiting an improved absorption rate while reducing an amount of a blowing agent used. The preparation method of a super absorbent polymer includes: preparing a monomer mixture including a water-soluble ethylene-based unsaturated monomer having at least partially neutralized acidic groups and an internal cross-linking agent; adjusting a dynamic pressure applied to the monomer mixture being transferred to 140 Pa or more by controlling a transfer rate while transferring the monomer mixture to a polymerization reactor; cross-linking and polymerizing the monomer mixture transferred to the polymerization reactor to form a hydrogel polymer; drying, pulverizing and classifying the hydrogel polymer to form a base resin powder; and further cross-linking a surface of the base resin powder in the presence of a surface cross-linking agent to form a surface cross-linked layer.
