Abstract
The invention relates to a method of synthesizing less toxic, sustainable bisphenols having a coumarin-type structure and the polymers derived therefrom. The method synthesizes the bisphenolic coumarins from biologically derived phlorogincol and β-keto esters. The bisphenolic coumarins can be converted coumarin-based polymers including engineering thermoplastics and high-performance thermosetting resins.
