Abstract
New polyether substituted benzoxazine monomers were synthesized starting from bisphenol A and p-Cresole as phenolic component and various polyetheramines. The chemical structures were proved by FTIR, 1H-NMR, 13C-NMR, 15N-NMR and gel permeation chromatography (GPC). The new benzoxazines were mixed with classical benzoxazine based on bisphenol A and benzylamine (BA-BZA) and reinforced with modified montmorillonite to give nanocomposites which were characterized by transmission electron microscopy (TEM). The structure of the nanocomposite is exfoliated only when a high compatibility is ensured between the benzoxazine comonomers and the modified montmorillonite, this being the case for the benzoxazine substituted with the same chain as that of modifier agent for montmorillonite.
