Analytical Method for Chain Entanglement in Super Absorbent Polymer Resin and Analytical System Using the Same

摘要

The present invention provides a method for preparing a superabsorbent resin, comprising: a) measuring a T2 relaxation time of a superabsorbent resin in powder form; (b) the high water-absorbent resin was swollen in D ₂ O and measuring the relaxation time T2; And (c) determining the amount of physical crosslinking through the difference in the T2 relaxation time of the step (a) and the step (b), and to an analysis system using the method .
