Water-absorbent resin particles via organic main group element catalysts

The invention changes the chemical composition parameters by introducing organic main group element compounds (containing I, Te, Sb, or Bi) as polymerization catalysts or additives during the polymerization process. This parameter change enables the formation of a polymer structure that simultaneously achieves high water retention capacity and sufficient gel strength, resolving the contradiction between these two properties.

The invention optimizes the crosslinking density parameter within a specific range (0.01-5 mol% based on monomer total) and combines it with the addition of organic main group element compounds. This parameter optimization enables the polymer to achieve adequate gel strength while maintaining high water retention capacity, resolving the trade-off between these two properties.

The invention adjusts the gel strength parameters through controlled crosslinking and the addition of organic main group element compounds to achieve an optimal balance. The resulting gel structure has sufficient strength to maintain absorption under load while preserving adequate liquid permeation rate, resolving the contradiction between these two performance metrics.
