Title (EN) RHEOLOGICALLY DEFINED LIGNIN COMPOSITIONS
(FR) COMPOSITIONS DE LIGNINE RHÉOLOGIQUEMENT DÉFINIES
Abstract:
(EN) 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.
(FR) L'invention concerne des dérivés anthropogènes de lignine naturelle, possédant des propriétés viscoélastiques spécifiques qui facilitent sélectivement la transformation de ces dérivés de lignine en produits finis particuliers. De tels dérivés de lignine sont caractérisés par des propriétés rhéologiques qui comprennent un module de conservation minimal (G'min), un début de température de ramollissement (T1) et/ou de température de réticulation (T2) d'un comportement principalement visqueux à principalement élastique.
