摘要： Disclosed are methods for producing a downstream product from cellulosic material by: a) contacting the cellulosic material with a polymer and a solvent to form a reaction mixture, where the polymer includes acidic monomers and ionic monomers connected to form a polymeric backbone, and each of the ionic monomers independently comprises at least one nitrogen-containing cationic group or at least one phosphorous-containing cationic group; b) degrading the cellulosic material in the reaction mixture to produce a liquid phase and a solid phase, where the liquid phrase includes one or more sugars, and where the solid phase includes residual cellulosic material; and c) using the one or more sugars to produce the downstream product.

摘要： Polymers including acidic monomers and ionic monomers connected to form a polymeric backbone are disclosed. The polymers may also include, e.g., acidic-ionic monomers within the polymeric backbone. Each acidic monomer may independently include at least one Bronsted-Lowry acid, and each ionic monomer may independently include at least one nitrogen-containing cationic group or phosphorous-containing cationic group. The acidic monomers and ionic monomers may make up, e.g., at least about 30% of the monomers of the polymer, based on the ratio of the number of acidic monomers and ionic monomers to the total number of monomers present in the polymer. The total number of ionic monomers may, e.g., exceed the total number of acidic monomers in the polymer. The polymer may be substantially insoluble in water.
