Photo of The figure shows two-dimensional NMR spectra of control (unreacted) loblolly pine and loblolly pine that has been reacted with a model compound of pMDI adhesive. The labels A, B, and C (and α, β, γ positions) relate to the chemical structures at the bottom of the figure. The contours labeled with a subscript r show reacted wood cell wall polymers. The reactivity of the lignin sidechains clearly dominates over all other wood cell wall polymers. Forest Service
