Xylan is a hemicellulose which is found abundantly in nature. In this work a novel polyurethane was developed involving xylan and tolylene-2,4-diisocyanate (TDI). Polymer synthesis was achieved via conventional heat or microwave-assisted reaction in dimethylsulfoxide. Because xylan has multiple OH groups on each polymer chain, the TDI/xylan molar ratio had to be adjusted in order to produce a soluble polymeric product. The reaction products were characterized by <sup>13</sup>C NMR, FT-IR, thermogravimetric analysis and differential scanning calorimetry. The xylan polyurethane was shown to exhibit improved thermal stability over xylan.
