    Abstract: A method of drying an absorbent polymer includes providing the absorbent polymer. A surfactant having a C10 to C24 ester group is incorporated with the absorbent polymer. An acid value of the surfactant is increased to further increase drying efficiency of the absorbent polymer. More specifically, after increasing the acid value of the surfactant, the absorbent polymer exhibits improved pumpability and spreadability, as compared to absorbent polymers including the surfactant without having the acid value of the surfactant increased.
