J. Economy et Ag. Andreopoulos, FACTORS WHICH INFLUENCE THE HIGH-TEMPERATURE ADHESIVE CHARACTERISTICSOF LIQUID-CRYSTALLINE COPOLYESTERS, The Journal of adhesion, 40(2-4), 1993, pp. 115-125
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 r
ecently reported 73/27 system. A tetramer of HBA/HNA with a compositio
n of 24/76 was synthesized to examine the effect on adhesion of wettin
g of the substrate at much lower temperatures. From the results of thi
s study it is now possible to define approaches for achieving very goo
d adhesion characteristics at temperatures well in excess of 250-degre
es-C.
