Liquid crystalline copolyesters of p-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid, with compositions 20/80 and 24/76, were studied in order to evaluate the effect of higher melting HBA/HNA copolyesters on the high temperature adhesive properties compared with data for the recently reported 73/27 system. A tetramer of HBA/HNA with a composition of 24/76 was synthesized to examine the effect on adhesion of wetting of the substrate at much lower temperatures. From the results of this study it is now possible to define approaches for achieving very good adhesion characteristics at temperatures well in excess of 250-degrees-C. (EN)
