Synthesis of novel vinylester from biobased phloroglucinol

Abstract

For the first time a vinyl ester network was synthesized from biobased phloroglucinol. This biobased molecule has an interesting chemical structure with an aromatic ring and three phenol functions. Phloroglucinol was epoxided, then methacrylated, prior copolymerization with styrene. Vinyl ester material has been formulated by copolymerization with styrene. This obtained material presents high thermal stability and thermomechanical properties, higher than those of Bisphenol A (BPA)-derived vinyl esters. Therefore phloroglucinol could interestingly be a possible substituent of BPA in such thermoset networks for composites.
