Claims33
A polymer comprising acidic monomers, ionic monomers, and acidic-ionic monomers connected to form a polymeric backbone,
- wherein each acidic monomer independently comprises at least one Bronsted-Lowry acid,
- wherein each ionic monomer independently comprises at least one nitrogen-containing cationic group or phosphorous-containing cationic group, and
- wherein each acidic-ionic monomer independently comprises at least one Bronsted-Lowry acid and at least one cationic group.
A composition comprising:
- biomass;
- and
- a polymer,
- wherein the polymer comprises acidic monomers and ionic monomers connected to form a polymeric backbone,
- wherein each acidic monomer independently comprises at least one Bronsted-Lowry acid, and
- wherein each ionic monomer independently comprises at least one nitrogen-containing cationic group or phosphorous-containing cationic group.
