For a long time it was deemed impossible to exceed an effective limit of 25 to 40% for incorporating lignin derivatives into plastics. However, two years ago it was disclosed that a series of thermoplastics containing 85% underivatized industrial kraft lignin had been successfully formulated for the first time. Now alkylated 95-100% kraft lignin based polymeric materials have been fabricated that possess tensile strengths and Young's moduli extending to 14 MPa and 1.3 GPa, respectively. Thus the feasibility of creating plastics composed almost entirely of simple lignin derivatives has been persuasively confirmed.
