The present invention provides manufacturing of and the use of novel polycarbamates and polycarbamides and their condensation reaction products formed by reacting with formaldehyde as wood composite binder resins and in other applications. These resins have thermosetting capabilities and usefulness as binders for wood and other materials with superior resin properties of low cost, colorlessness, exceptionally good binding, and fast curing characteristics, as well as very low formaldehyde emissions. The newly-designed and synthesized novel starting materials for the thermosetting resins of the present invention are diethylene tricarbamide and various polycarbamates derived from corresponding polyols.

The synthesis of various new polyvalent nitrocarbamates derived from sugar alcohols was accomplished by an economically benign two‐step synthesis. The precursor carbamates were synthesized with the reagent chlorosulfonyl isocyanate (CSI) and further nitrated using mixed acid. The starting materials, sugar alcohols, are renewable biomass, mainly used in food and cosmetic industry. The structures of
