  • Patent number: 11949137
    Abstract: The present invention belongs to the field of alkaline polymer electrolyte membranes, and relates to a comb-shaped structure polybenzimidazole anion exchange membrane with high conductivity and preparation method thereof. In the invention, firstly, polybenzimidazole is grafted with the non-cationic side chains to the max grafting rate to synthesize the de-protonated comb-shaped polybenzimidazole material, avoiding the N—H in benzimidazole forms ionic binding with cationic functional groups, which will reduce the reactivity and mobility of cationic groups; then react de-protonated comb-shaped polybenzimidazole with quaternization reagent to attach the pendent side chain with cationic functional groups, making it easy to aggregate to form ion clusters and hydrophilic/hydrophobic microphase separation. The anion exchange membrane prepared in this invention has excellent conductivity, mechanical properties and alkaline stability.

  • Publication number: 20200406232
    Abstract: Chromatography resins having anionic exchange-hydrophobic mixed mode ligands, that are useful for purifying target biomolecules using anionic exchange (i.e., where the ligand is positively charged) and hydrophobic mixed mode chromatography. The chromatography resins allow for efficient purification of target biomolecules (e.g., recombinant proteins, antibodies, antibody-drug conjugates, or antibody derivatives including, but not limited to, antibody fragments and antibody fusions) from a sample, and have been found to be useful in purifying monomeric target biomolecules from aggregate target biomolecules. In an embodiment, the chromatography resins are useful for separating antibodies from one or more components (e.g., contaminants) in the sample.
