Kraft lignin-based thermoplastics blends

Figure 5. Tensile behaviour to point of ftacture for 85% kraft lignin-based thermoplastic blends with poly(vinyl acetate) in presence of diethyleneglycol dibenzoate (1.6%) and indene (0.8%). Stress-strain a-e curves determined for material test pieces at strain rate of 4.5 x 10" sec" graphical data from reference 1.

Be that as it may, some important insight at the molecular level into the constitution of the 85% kraft lignin-based thermoplastics was furnished by a small modification to the formulation that had been developed for these blends. As already mentioned (see section 2.1), kraft lignin preparations are...
