| Abstract: | The absorbency data of super absorbent polymers under various leaching time were measured by changing mass of exsiccated polymers or time of absorbing or initiative water volume. After analyzing the curves of absorbency via leaching time, optimum conditions for measuring absorbency of super absorbent polymers have been obtained, namely mass of exsiccated polymers is 0.300 0 g and time of absorbing is 30 min and initiative water is 2 000 times and leaching time is 30 min, which lays a foundation normalization of measuring condition for absorbency of super absorbent polymers. |
