  • Macromonomers and bottle brush polymers for delivery of biological agents
    Patent number: 11986533
    Abstract: A composition includes a macromolecular polyacrylamide copolymer excipient with an ?-end including a ROMP-active norbornene end-group and a ?-end including a terminal monomer with an end group chosen from: a hydrogen atom (H); or a functionalized acrylate with functionality chosen from alkyl, hydroxyl (OH), methyl-polyethylene glycol ((PEG)-CH3), hydroxy-PEG (PEG-OH), carboxylic acid (COOH), and combinations thereof. A biological compound chosen from active pharmaceutical ingredients, proteins, polynucleotides, and mixtures and combinations thereof is non-covalently bound with the macromolecular excipient.
    Type: Grant
