  • Thermoplastic polymers synthesized from depolymerized lignin via free radical polymerization
    Patent number: 11912805
    Abstract: One aspect of the present application relates to a method of synthesizing a thermoplastic polymer. This method includes providing a depolymerized lignin product comprising monomers and oligomers and producing lignin (meth)acrylate monomers and oligomers from the depolymerized lignin product. A thermoplastic lignin (meth)acrylate polymer is then formed by free radical polymerization of the lignin (meth)acrylate monomers and oligomers. The present application also relates to a branched chain thermoplastic lignin (meth)acrylate polymer which includes a chain transfer agent. The thermoplastic lignin based polymers of the present application can be used to prepare carbon fibers, and engineering thermoplastics. Mixtures of lignin (meth)acrylate monomers and oligomers are also disclosed.
