A crosslinked polymer composition comprising: (i) a base polymer containing a multiplicity of at least one type of functional group selected from amino, amido, thiol, carboxylic acid, carboxylic acid ester, and epoxy groups; (ii) a multiplicity of hydroxylated benzene rings covalently linked to the base polymer, wherein each hydroxylated benzene ring contains at least two hydroxy groups, and with at least two of the hydroxy groups on said hydroxylated benzene rings being free as OH groups; and (iii) a multiplicity of crosslinking groups that crosslink at least two of said functional groups in the base polymer. The invention is also directed to lithium-ion batteries in which the above-described composition is incorporated in an electrode of the battery, and also directed to methods of operating a lithium-ion battery in which the above-described crosslinked polymer composition is incorporated in an electrode thereof.

A chitosan-latex binder comprising chitosan and latex binder in a weight ratio of chitosan to latex binder of from about 1:10 to about 1:15,000. A method of making a chitosan-latex binder, the method comprising (a) contacting chitosan with an acidic solution to form a chitosan solution, and (b) contacting at least a portion of the chitosan solution with a latex binder to form the chitosan-latex binder, wherein the chitosan-latex binder is characterized by a chitosan to latex binder weight ratio of from about 1:10 to about 1:15,000.

It is disclosed chitosan-reinforced urea-formaldehyde (UF) adhesives for bonding wood-based composites, such as plywood and particleboard, or other fibrous materials and the method of producing the adhesives. The adhesives are produced by mixing unmodified chitosan containing raw material and a urea-formaldehyde resin to produce wood composite adhesive resins.
