| Popis: | Epoxy resins were prepared from di-α-naphthol(4,4′-dihydroxy-1,1′-dinaphthyl) and di-β-naphthol(2,2′-dihydroxy-1,1′-dinaphthyl). The resins consisted mainly of the reaction product of 1 mole of dinaphthol with 2 moles of epichlorhydrin. They contained chlorine, however, and were correspondingly deficient in diepoxide functionality. The resins from di-α-naphthol were crystalline, had m.p. 200°C., and were not miscible with conventional curing agents. Di-β-naphthol gave resins with softening points in the range 50–70°C., which cured with diethylenetriamine or the anhydrides of dibasic acids, giving hard but brittle products. The brittleness was not removed by curing with plasticizing curing agents, such as tetrapropenyl succinic anhydride. The cured di-β-naphthol-based resins had thermal stabilities similar to analogous epoxy resins based on bisphenol A. |
