Abstract

Abstract The preparation of soluble and processable polybenzoxazine precursors capable of forming high performance networks is an important field of research with a broad spectrum of application. This study demonstrates an approach that utilizes aromatic sulfonediamine, bisphenol-A, and formaldehyde in Mannich-type polycondesation to prepare polybenzoxazine precursor. The structure of the oligomeric precursor (M n= 2600) ...
