Abstract
A novel wholly aromatic thermotropic liquid crystal polyester consisting essentially of 4-oxybenzoyl unit, terephthaloyl unit, 4,4'-dioxydiphenyl unit and 4,4'-dioxydiphenyl ether unit has a relatively low transition temperature to liquid crystal as well as good flow characteristics, and has thereby good melt-formability. The polyester gives melt extruded fibers and melt extruded films having superior mechanical strengths and elastic moduli, and also gives injection-molded products having superior strengths, excellent thermal characteristics, elastic moduli and impact strengths.
