Lignin is the second most abundantly available biopolymer from the biomass resources; however, it is the most underutilized material so far. Lignin is an amorphous, polyphenolic structure enzymatically synthesized inside the plant cells [19, 20].The
For the first time, the coordination-based energy sacrificial bonds have been constructed in the interface between lignin and polyolefin elastomer for preparing a new class of high performance thermoplastic elastomers (TPEs)

Then, various copolymerization methodologies of lignin applicable for thermoplastic monomers are reviewed. Lastly, the lignin based thermoplastic blends are discussed which covers the lignin blends with various thermoplastic polymers and the
Plasticizers depress the glass transition temperature (Tg) of polymers and produce a flowable material at lower temperatures. The use of plasticizers to depress Tg of lignin is important, since at high processing temperatures lignin crosslinks, making it intractable. The
