  • SUPERABSORBENT POLYMER COMPOSITION AND METHOD OF MANUFACTURING SUPERABSORBENT POLYMER
    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.
