ABSTRACT:
A polymer blend which is capable of exhibiting an anisotropic melt phase and which is capable of forming shaped articles which exhibit satisfactory mechanical properties is provided. The polymer blend comprises approximately 5 to approximately 95 percent by weight, based upon the total weight of the blend, of a first melt processable wholly aromatic polyester which is capable of forming an anisotropic melt phase apart from the blend and which comprises not less than approximately 10 mole percent of recurring units which include a naphthalene moiety, and approximately 5 to approximately 95 percent by weight, based upon the total weight of the blend, of a second melt processable wholly aromatic polyester which is capable of forming an anisotropic melt phase apart from the blend (as defined).
