Carborane-containing homo- and copolyarylates were prepared by accepto
r-catalytic polyesterification in solution from m-carboranedicarboxyli
c acid and 4,4'-dioxydiphenyl-o-carborane in combination with common d
icarboxylic acids and bisphenols. The properties of the resulting poly
arylates were studied, and the factors affecting the development of li
quid-crystalline order in carborane-containing copolyarylates were dis
cussed.
