description The invention discloses a method for testing the influence produced by a neutralization degree on composite water-absorbent resin volume phase transition. The method provided by the invention comprises the following steps of preparing composite water-absorbent resin powder for the next use through a hydrophobic high-strength resin synthesis technology capable of controlling a cross-linking agent use amount, putting the composite water-absorbent resin powder into multiple beakers, adding absorbed solutions having different neutralization degrees into the beakers, removing free water by filtration when the composite water-absorbent resin powder is fully swelled, respectively calculating volume phase transition values under different neutralization degree conditions according to liquid level lifting heights, and comparing the volume phase transition values to determine the influence produced by a neutralization degree on composite water-absorbent resin volume phase transition. The method provided by the inventio
