Publication number: 20200399431Abstract: The present invention relates to a covalently cross-linked hyaluronic acid aerogel, a hydrogel, and a preparation method thereof. The method includes steps of: taking hyaluronic acid as a raw material to prepare a hyaluronic acid aqueous solution; taking 1,4-butanediol diglycidyl ether, ethylene glycol diglycidyl ether, or polyethylene glycol diglycidyl ether as a crosslinking agent; promoting a chemical crosslinking through covalent bonds between the crosslinking agent and the hyaluronic acid by a freeze-drying technique to obtain a covalently cross-linked hyaluronic acid aerogel; furthermore, soaking the covalently cross-linked hyaluronic acid aerogel in purified water, which absorbing water and swelling to obtain a covalently cross-linked hyaluronic acid hydrogel. The covalently cross-linked hyaluronic acid aerogel has good liquid absorption properties, and can quickly absorb water and swell to the covalently cross-linked hyaluronic acid hydrogel.Type: ApplicationFiled: June 21, 2019Publication date: December 24, 2020Applicant: Hunan Elixer Therapeutics Co., Ltd.Inventors: Yu Huang, Bihuang Hu

Publication number: 20200399434Abstract: A method for producing a flexible-packaging film in which a first substrate and a second substrate are laminated with a reactive adhesive of a polyisocyanate composition (X) and a polyol composition (Y) therebetween includes a two-component separate application step in which a liquid mixture applied to the first substrate and including the polyisocyanate composition (X) and the polyol composition (Y), and a catalyst (Z) formed in a dot pattern on the second substrate are brought into contact with each other to achieve contact-bonding together. The substrates are preferably plastic films, metal vapor-deposition films, or metal foils. As the second substrate, a non-oriented film is preferably employed.Type: ApplicationFiled: February 14, 2019Publication date: December 24, 2020Applicant: DIC CorporationInventors: Kiyomi Hata, Shigekazu Takahashi
