  • Patent number: 12168718
    Abstract: Block copolymers have a general chemical structure of one of the formulas [A]n-[B]m and [B]n-[A]m, wherein block [A] is a poly(2-oxazine) and wherein block [B] is a poly(2-oxazoline). The block copolymers have desired thermogelling and rheological properties and are useful as carrier materials for active ingredients such as drugs, cells, proteins, and other active ingredients.

    Inventors: Thomas Lorson, Robert Luxenhofer
  • Patent number: 12139579
    Abstract: Provided is a block copolymer comprising a polymer block (A) formed from repeating units of formula (I): wherein R1 is methyl or ethyl, and a polymer block (B) formed from repeating units of formula (II): as well as a hydrogel comprising the block copolymer.
    Type: Grant
    Filed: September 4, 2020
    Date of Patent: November 12, 2024
    Assignee: Julius-Maximilians-Universität Würzburg
    Inventors: Robert Luxenhofer, Lukas Hahn
  • Publication number: 20240299627
    Abstract: Provided is a block copolymer comprising a polymer block (A) which comprises repeating units of formula (I) and a polymer block (B) which comprises repeating units of formula (II), wherein R1 is methyl or ethyl, and R2 represents a group —CH2—CH2-phenyl. The copolymer of the present invention allows a rapid thermoresponsive inverse gelation to be achieved, yielding a hydrogel with viscoelastic solid-like properties, as well as shear thinning, rapid structure recovery and good strain resistance properties. The hydrogel can be favorably used in 3D printing applications.

  • Patent number: 12018125
    Abstract: Provided is an (A)-(B)-(A) triblock copolymer comprising two hydrophilic polymer blocks (A) as further defined herein, and a polymer block (B), said polymer block (B) comprising at least one type of repeating unit of the following formula (I) wherein R1 is an aliphatic hydrocarbon group which is optionally substituted with one or more of —OR5, —SR5, —NR6R7, —(NR6R7R8)+, —CONR6R7, —C(O)OR9 and —C(O)R10, wherein R5 to R10 are independently selected from H, aliphatic and aromatic residues, and wherein R1 is selected such that the polymer block (B) is more hydrophobic than the polymer block (A); and compositions, such as pharmaceutical compositions, formed with the block copolymer.
