    摘要: The invention relates to anionically modified copolymers that can be produced by the polymerization of monomers (A), (B) and (C) to obtain non-ionic polymers with reactive terminal OH groups and by the subsequent reaction of the terminal OH groups to form anionic end groups. According to the invention, (A) is a monomer of formula (I), in which A represents C2-C4 alkene and B represents a C2-C4 alkene that is different from A, R represents hydrogen or methyl, m is a number between 1 and 500, n is a number between 1 and 500, (B) is an ethylenically unsaturated monomer containing an aromatic group and (C) is a ethylenically unsaturated monomer.

    摘要: The invention pertains to, for example, an improved sorbent and process for removing fermentation inhibitors such as furfural and/or HMF in microbial processes utilizing fermentable sugars obtained from biomass including, for example, in the production of bioalcohols. The sorbent is capable of separating one or more inhibitors from monosaccharides and is characterized by: (1) a Ksugar partition coefficient of less than about 5 and (2) one or more of the following characteristics: (a) a furfural sorption capacity of at least about 200 mg/g sorbent at a furfural solution concentration of 2.5 grams per liter of water; (b) an Mt/M∞ of at least about 0.9 at 7.5 sec1/2; and (c) a Kfurfural partition coefficient of greater than about 3000.
