RHEOLOGICALLY DEFINED LIGNIN COMPOSITIONS

摘要

Anthropogenic derivatives of native lignin are disclosed, having specific viscoelastic metrics which selectively facilitate the processing of these lignin derivatives into particular finished products. Such lignin derivatives are characterized by rheological metrics that include minimum storage modulus (G'min), onset of softening temperature (T1), and/or cross-over temperature (T2) from predominately viscous to predominately elastic behaviour.
