A thermoplastic wholly aromatic copolyimide ester consisting essentially of the recurring unit (I) represented by the following formula:
the recurring unit (II) represented by the following general formula:
wherein
n is an integer of 0 or 1;
the recurring unit (III) represented by the following formula:
wherein the two carbonyl groups are present at para position or meta position of the benzene nucleus to each other;
and the recurring units (IV 1) or (IV 2) represented respectively by the following formulas:
wherein
-Q- is -0- or -CO-
and each Q is present at para position or meta position of the benzene nucleus respectively to the imide group,
or
with the proviso that the recurring units (I), (II), (III), and (IV) are bonded to form ester bonds,
and wherein the thermoplastic wholly aromatic copolyimide ester has a melt viscosity of from 1.0 to 1.0 x 105 Pa•s as measured at a shear stress of 0.025 Mpa and at a temperature of from 300 to 400° C
