The technical lignin compositions can include at least about 50 wt% phenolic polymers and/or at least about 75 wt% combined phenolic monomers and phenolic polymers. In some aspects, less than about 50 wt% of the linkages between benzylic units in the phenolic polymers and/or in the composition can correspond to [3- 0-4 linkages. At least about 50 wt% of the hydroxyl groups in the composition can correspond to phenolic hydroxyl groups. At least about 60 wt% of the phenolic hydroxyl groups and/ or phenolic ether groups can correspond to phenolic hydroxyl groups and/or phenolic ether groups in an ortho position relative to at least one substituent.
