  • Publication number: 20240131048
    Abstract: The present disclosure includes cationic carrier units comprising (i) a water-soluble polymer, (ii) a positively charged carrier, (iii) a hydrophobic moiety, and (iv) a crosslinking moiety, wherein when the cationic carrier unit is mixed with an anionic payload (e.g., an antisense oligonucleotide) that electrostatically interacts with the cationic carrier unit, the resulting composition self-organizes into a micelle encapsulating the anionic payload in its core. The cationic carrier units can also comprise a tissue specific targeting moiety, which would be displayed on the surface of the micelle. The disclosure also includes micelles comprising the cationic carrier units of the disclosure, methods of manufacture of cationic carrier units and micelles, pharmaceutical compositions comprising the micelles, and also methods of treating diseases or conditions comprising administering the micelles to a subject in need thereof.

  • Patent number: 10975184
    Abstract: The present invention relates to a high-density ethylene-based polymer and a pipe using the same, the high-density ethylene-based polymer including: an ethylene homopolymer; or a copolymer of ethylene and at least one comonomer selected from the group consisting of an ?-olefin, a cyclic olefin and linear, branched and cyclic dienes. The pipe using the high-density ethylene-based polymer of the present invention has more superior strain hardening than a conventional polyethylene resin pipe, and thus has excellent long-term pressure resistance characteristics and processability.

  • Publication number: 20210002463
    Abstract: Provided are an ethylene-based polymer having excellent long-term pressure resistance characteristics and a pipe using the ethylene-based polymer. The ethylene-based polymer satisfies the balance of mechanical characteristics and excellent molding processability, as compared with a conventional ethylene-based polymer. Also provided are an ethylene-based polymer having a wide molecular weight distribution and a small lamellar thickness, thereby increasing tie molecules and obtaining excellent long-term pressure resistance characteristics, and a pipe using the same.
