ABSTRACT:
A novel polyester is provided which forms an anisotropic melt phase in combination with good heat resistance and melt-processability. The polyester is formed from a combination of appropriate concentrations of four essential constituent units (as described). In a particularly preferred embodiment the polyester is derived from p-acetoxybenzoic acid, 4,4'-diacetoxydiphenyl, 2,2-propylidenebis(1,4-phenylene), and terephthalic acid. The resulting polyester is well suited to injection molding to form superior three-dimensional articles, fibers and films.
