This invention relates to polymerization of muconic acid and its derivatives. Muconic acid useful for the invention can be in any of its isomeric forms including cis, cis-muconic acid (ccMA), cis, trans-muconic acid (ctMA), and trans, trans-muconic acid (ttMA). Muconic acid used in the invention can be derived either from renewable carbon resources through biological fermentation or from non-renewable petrochemical resources through biological fermentation or chemical conversion.
