  • Superabsorbent polymer and the method of fabricating the same
    Patent number: 10731024
    Abstract: A superabsorbent polymer includes polymer particles, surface cross-linking agents and particles made of silicon-containing inorganic salt. The polymer particles have cross-linking inside the polymer particles. The surface cross-linking agents are covalently bound to the surface of the polymer particles so as to constitute a surface cross-linked region at the surface of each said resin particle, and the particles made of silicon-containing inorganic salt cover the surface of the polymer particles.
    Type: Grant
    Filed: December 4, 2017
    Date of Patent: August 4, 2020
    Assignee: FORMOSA PLASTICS CORPORATION
    Inventors: Zhong-Yi Chen, Yu-Yen Chuang, Li-Han Huang, Yu-Sam Lin, Feng-Yi Chen, Ching-Hua Liang
  • Superabsorbent polymer and the method of fabricating the same
    Patent number: 10550243
    Abstract: A superabsorbent polymer includes polymeric particles, surface cross-linking agents and an extract of a plant of Sapindaceae. The polymeric particles have cross-linking inside the polymeric particles. The surface cross-linking agents are covalently bound to the surface of the polymeric particles so as to constitute a layer of surface cross-linked region at the surface of each polymeric particle, and the extract of the plant of Sapindaceae covers the surface of the polymeric particles.
