A copolymer includes a main hydrocarbon chain and side groups including carboxylic groups and polyoxyalkylate groups. The copolymer further includes gem-bisphosphonate groups. The copolymer can be included in an admixture for suspensions of mineral particles and in a composition of mineral particles. The copolymer can also be used for fluidifying and maintaining fluid, suspensions of mineral particles and for reducing the sensitivity of hydraulic compositions to clays and alkaline sulfates.

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.
