Novel biorenewable bisphenols are obtained through simple and rapid chemical transformation of the natural product trans‐anethole. The corresponding dicyanate esters are thermally cured to give polycyanurate networks. The thermal properties from differential scanning calorimetry, thermogravimetric, and dynamic thermomechanical analyses of the new dicyanate esters compare favorably with similar commercial products. © 2012 Wiley Periodicals, Inc.† J Polym Sci Part A: Polym Chem, 2012
The natural product trans‐anethole, which is a common flavor and fragrance raw material isolated on large scale from star anise, is converted into two new dicyanate esters. These dicyanates undergo polymerization to heat‐resistant polycyanurate networks. Thermal analysis shows these biobased polycyanurate thermosets are equal to or better than that obtained from commercial cyanate esters derived from petrochemical feedstock.
