  • Publication number: 20250051525
    Abstract: The present invention relates to a hydroxylphenyl-terminated polysiloxane, a polysiloxane-polycarbonate copolymer comprising the same as repeating unit, and a method for preparing the copolymer, and more specifically, a polysiloxane of a specific structure having terminal silane unit comprising optionally substituted hydroxylphenyl group, and a polysiloxane-polycarbonate copolymer which comprises the polysiloxane and a polycarbonate block as repeating units, and thereby shows the same or more excellent transparency and significantly further improved flame retardancy as compared with the level of conventional polysiloxane-polycarbonate copolymer, and a method for preparing the same.

  • Patent number: 9211343
    Abstract: Provided are an siRNA-polymer conjugate, and a method for preparing the same, and more specifically, to a hybrid conjugate formed by covalently bonding siRNA and a polymeric compound for improving the in vivo stability of siRNA, and to a preparation method of the hybrid conjugate. The conjugate of the present invention can improve the in vivo stability of siRNA, thereby achieving an efficient delivery of therapeutic siRNA into cells and exhibiting the activity of siRNA even with a small dose of a relative low concentration. Therefore, the conjugate can advantageously be used as not only an siRNA treatment tool for cancers and other infectious disease, but also a novel type siRNA delivery system.
