Abstract: The dynamic curing behavior of two curing systems which include pristine polybenzoxazine monomer(BZ) system and polybenzoxazine monomer insertion montmorillonite(BZ/MMT) system was compared. It was found that the organically treated played a vital role in curing behavior of BZ/MMT system and two types of curing reactions occurred in BZ/MMT system which includes: catalyzed polymerization and thermal polymerization, as a result, big difference in the two systems occurred at the characteristic curing temperature, curing rate, the heat of reaction, reaction order, as well as apparent activation energy.

Key words: Polybenzoxazine, Montmorillonite, Dynamic curing behavior
