| description | A novel polyester is provided which has been found to exhibit a thermotropic melt phase at a temperature which enables it readily to undergo melt processing to form quality fibers, molded articles, etc. The polyester of the present invention is formed primarily of recurring 6-oxy-2-naphthoyl and p-oxybenzoyl moieties in the proportions indicated. The hydrogen atoms present upon the aromatic rings of these moieties optionally may be at least partially substituted (as described). Also, minor amounts of other ester-forming moieties may be included in the polyester so long as the thermotropic character and ease of melt processability is retained. In a preferred embodiment the wholly aromatic polyester is capable of undergoing melt processing at a temperature below approximately 325 DEG C., and in a particularly preferred embodiment at a temperature of approximately 280 DEG to 300 DEG C. |
