Abstract
A super absorbent polymer may exhibit improved absorption rate and absorption performance. The super absorbent polymer may be a polyacrylic acid or salt thereof-based super absorbent polymer. The superabsorbent polymer may have a value F1 from 0.55 to 0.65 calculated by Equation 1: F1=K1(0.5)×[{(A(CRC)×C(Convexity)×D(Circularity))}/(B(Aspect ratio))]. The superabsorbent polymer may have a value F2 from 0.65 to 0.75 calculated by Equation 2: F2=K2×[(B)/{(A×C×D)}]. The variables included in Equations 1 and 2 are described in detail in the disclosure.
