Claim Text:
1. A block polymer comprising at least one A-block and at least one B-block, wherein the A-block contains a polymerized lignin-based monomer or polymerized combination of lignin-based monomers, wherein said lignin-based monomer or monomers have the general formula Ar—O—C(═O)—C(R)═CH 2 or Ar—O—C(═O)—C(R)═CHCO 2 H, where Ar is an aromatic residue obtained from a cresol, a xylenol, a guaiacol, a catechol, a syringol, a vanillin or a combination thereof, and R is H or CH 3 , and the B-block contains a polymerized fatty acid-based monomer, polymerized fatty alcohol-based monomer or a polymerized combination of fatty acid-based monomer(s) or fatty alcohol-based monomer(s).
