Artificial derivatives of natural lignin with specific viscoelastic indices are disclosed that selectively promote the processing of lignin derivatives into specific finished products. The lignin derivative is characterized by a minimum storage modulus (G' min ), a softening initiation temperature (T 1), and/or a crossover temperature (T 2 ), including a change from a strong viscous state to a strong elastic state. .
