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.

Provided are a UV-curable non-isocyanate polyurea polymer and a UV-curable coating composition containing the same. The UV-curable non-isocyanate polyurea polymer has one or more ethylenically unsaturated functional groups and the ethylenically unsaturated functional groups are attached to nitrogen atoms present in a backbone urea segment via C(=0)- linkage. The nonisocyanate polyurea polymer is prepared by: (i) providing an ethylenically unsaturated compound having one or more carboxylic acid functional groups; and (ii) reacting said ethylenically unsaturated compound having one or more carboxylic acid functional groups with a multi-carbodiimide polymer to form the non-isocyanate polyurea polymer.
