Method of drying an absorbent polymer with a surfactant

摘要

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.
