Polyester resin exhibiting anisotropy in molten state and composition thereof.

摘要

A liquid crystal polymer having a good balance between high processability and heat resistance is provided by a polyester resin exhibiting anisotropy in the molten state which comprises constituent units represented by the formulae (I) to (III) as indispensible components in amounts of 35 to 90% by mole, 0.5 to 30% by mole and 0.5 to 30% by mole respectively: <CHEM>
