SYNTHESIS OF AROMATIC-HETEROCYCLIC POLYMER FROM PRECURSOR PRODUCED BY BIOSYNTHESIS

摘要

2,4-Polybenzoxazoles are synthesized from a biosynthetically prepared AB monomer. The biosynthetically produced precursor, 2,3-dihydro-3- hydroxyanthranilic acid (DHAA), is chemically transformed to the AB monomer, 3-hydroxyanthranilic acid (HAA). This AB monomer is used to prepare said polybenzoxazoles.
