  • HIGH VALUE LIGNIN DERIVATIVES, POLYMERS, AND COPOLYMERS AND USE THEREOF IN THERMOPLASTIC, THERMOSET, COMPOSITE, AND CARBON FIBER APPLICATIONS
    Publication number: 20160222045
    Abstract: The present disclosure relates to reactive modified lignin, methods of preparing such modified lignin, and materials, such as polymer systems, incorporating the modified lignin. More specifically, the lignin can be modified by selectively masking reactive functional groups such that the material has a modulated reactivity and is thus better suited for incorporation into and/or formation of further materials, such as carbon fibers.
    Type: Application
