Abstract:
1. An aqueous binder composition substantially free of polycarboxylic acids comprising (i) one or more diprimary diamine or poly(primary amine), and (ii) one or more 5-carbon reducing sugar chosen from xylose, ribose, arabinose, lyxose, or xylulose; an optical isomer thereof; a hydroxy, halo, alkyl, alkoxy or carbonyl substituted reducing monosaccharide; and a dehydrated reducing monosaccharide; wherein the number of equivalents of primary amine relative to the number of equivalents of carbonyl groups in the 5-carbon reducing sugar, or the equivalent ratio, ranges from 0.2:1 to 1.6:1 with the equivalent ratio defined such that a composition having a 2:1 equivalent ratio of primary amine groups in a diprimary diamine to carbonyl groups in the 5-carbon reducing sugar equates to a composition having equal moles of a diprimary diamine and a reducing sugar having one carbonyl group, and, further wherein, when (i) is a poly(primary amine), it is a polyamine having a weight average molecular weight of 5,000 or less and 10 wt. % or more of primary amine groups, based on the total weight of the polyamine.
