Table 3: DSC data. The spherical shape of the obtained materials was confirmed by photomicrographs, as shown in Figure 5. All the samples contain microspheres of different sizes. Materials with unmodified lignin had much smaller diameters (9-21 \(\upmu\)m) than those with modified lignin (35-63 \(\upmu\)m). Materials with modified lignin and DVB had the largest diameters in the range of 45-63 \(\upmu\)m, and the microspheres with modified lignin from hardwood (EL-ea-Met and EL-e-Met) had larger diameters (49-63 \(\upmu\)m) than \begin{table}
