Abstract
A polyester resin comprises 35 to 90 mole percent of the unit (I), 0.5 to 20 mole percent of the unit (II), 0.5 to 45 mole percent of the unit (III), 0.5 to 45 mole percent of the unit (IV), and 0.5 to 45 mole percent of the unit (V), exhibiting the anisotropy in its molten state. A polyester composition comprises the polyester resin as defined above and up to 95 percent by weight of an inorganic filler.
