A binder comprising a polymeric binder comprising the products of a carbohydrate reactant and nucleophile is disclosed. The binder is useful for consolidating loosely assembled matter, such as fibers. Fibrous products comprising fibers in contact with a carbohydrate reactant and a nucleophile are also disclosed. The binder composition may be cured to yield a fibrous product comprising fibers bound by a cross-linked polymer. Further disclosed are methods for binding fibers with the carbohydrate reactant and polyamine based binder. 149.-. (canceled)50. A method of making a collection of matter bound with a polymeric binder comprising:preparing a solution containing reactants for producing the polymeric binder and a solvent, wherein the reactants include a carbohydrate reactant and a nucleophile wherein{'sub': 1', '2, '(a) the nucleophile is R-Q-R,'}(b) Q is alkyl, cycloalkyl, heteroalkyl, or cycloheteroalkyl, each of which is optionally substituted having a nucleophilic moiety and a stabilization moiety,{'sub': '1', '(c) Ris selected from the group consisting of an amine, an azide, a cyanate, an isocyanate, a thiol, a disulfide, a thiocyanate, a halogen, a haloformyl, a carboxyl, a carboxylate, a hydroxyl, and an alkoxide, and'}{'sub': '2', '(d) Ris selected from the group consisting of an amine, an amide, an imine, an imide, a nitro, a nitrate, a pyridine, a phosphate, a phosphono, a hydroxyl, a hydrogen, a sulphono, a sulpho, a sulfinyl, and a sulfhydryl;'}disposing the solution onto the collection of matter;volatilizing the solvent to form an uncured product, andcuring the uncured product to form the polymeric binder.51. The method of claim 50 , wherein the collection of matter includes fibers selected from the group consisting of mineral fibers claim 50 , aramid fibers claim 50 , ceramic fibers claim 50 , metal fibers claim 50 , carbon fibers claim 50 , polyimide fibers claim 50 , polyester fibers claim 50 , rayon fibers claim 50 , and cellulosic fibers.52.
