Abstract
Condensation of hexakis(methoxymethyl)melamine (HMMM) with 2,4-disubst ituted and Li-substituted phenols in refluxing p-xylene catalyzed by d inonylnaphthalenedisulfonic acid (DNNDSA) gives substituted s[3,4-dihy dro-1,3-(2H)-benzoxazin-3-yl]-s-triazine derivatives (1-4). These tris (benzoxazine) derivatives are characterized by infrared, H-1 and C-13 NMR, mass spectroscopy, and elemental analysis. Differential scanning calorimetry (DSC) studies suggest thermal cross-linking reactions of b enzoxazines made from 4-substituted phenols but not for the one made f rom a 2,4-disubstituted phenol.
