Latest Patents

Chung’s latest patents revolve around methods for preparing super absorbent polymers. The first patent involves a method that emphasizes appropriate control over the water content of the super absorbent polymer during hydration. This method aims to suppress crushing during transfer, thereby maintaining the integrity of the polymer. Additionally, it addresses the deterioration of the material's physical properties, which can be caused by the production of giant particles and the nonuniformity of water content during the hydration step.

The second patent also details a method for preparing super absorbent polymers, in which a mixture of polymer particles, water, and specific additives are combined to form a hydrated super absorbent polymer. The invention involves a base polymer powder that includes a cross-linked polymer created from a water-soluble ethylenically unsaturated monomer with an acidic group. Furthermore, a surface cross-linked layer is formed on the base polymer powder through additional cross-linking, enhancing the material’s properties. The method seeks to control water content effectively, thus preventing issues like crushing during transfer and maintaining the desired physical properties.
