Abstract

ABSTRACT A diethylphosphonate-containing benzoxazine compound (DEP-Bz) to be used as a multi-functional reaction agent for preparation of high performance polybenzoxazine thermosetting resins has been reported. The chemical structure of DEP-Bz has been characterized with FTIR, 1 H NMR, and elemental analysis. The phosphonate groups of DEP- Bz could convert into phosphonic acid groups which could catalyze the ring-opening ...
