  • Publication number: 20250018370
    Abstract: The present invention is related to a superabsorbent polymer composition and a method of manufacturing a superabsorbent polymer. The superabsorbent polymer composition includes a water solution containing carboxylic acid monomers, a hydrolyzed collagen, a crosslinking agent, and a polymerization initiator. The superabsorbent polymer composition includes a specific amount and a specific molecular weight of hydrolyzed collagen, and thus the obtained superabsorbent polymer has high absorbent properties and dryness properties as well as proper biodegradability.

  • Publication number: 20250010267
    Abstract: A superabsorbent polymers and a method of forming the same are provided. The method is processed by adding calcined shell powders to a free radical polymerization. The superabsorbent polymers with more micropores can be obtained. Therefore, absorptivity and permeability for the liquid of the superabsorbent polymers are increased, and diffusibility and liquid conductivity of the superabsorbent polymers are also improved.
