  • Patent number: 11926700
    Abstract: Biorenewable polyesters and polyester copolymers derived from camphoric acid, aromatic dicarboxylic acid and aliphatic diols and methods of making those copolyesters and articles comprising copolyesters are disclosed. The disclosed biorenewable copolyesters may can have a Mn of from about 5,000 Da to about 500,000 Da. Also disclosed are preparation methods of various monomers e.g., cis-1,4-anhydroerythritol and bis(2-hydroxyethyl) camphorate. The disclosed biorenewable polyesters and polyester copolymers can be used for production of various articles utilizing a conventional polyesters or polyester copolymers, to replace, in part or in whole, a conventional non-biorenewable polyesters or polyester copolymers.
