The present invention relates to a method for producing a super absorbent polymer which can reduce the variation in physical properties by controlling the temperature rise temperature in two stages during surface crosslinking. Specifically, the present invention relates to a method for producing a super absorbent polymer, which can shorten the temperature raising time during the manufacture of the super absorbent polymer, which facilitates control of the penetration depth of the surface crosslinked body and can improve physical properties. |
