Abstract: An improved process for producing a polymer blend which exhibits an anisotropic melt phase and is capable of forming shaped articles having satisfactory mechanical properties (e.g. tensile strength, flexural strength, and Izod impact strength) is provided. The process comprises the steps of (a) post-polymerizing a melt processable wholly aromatic polyester which is capable of forming an anisotropic melt phase apart from the blend and (b) subsequently intimately mixing together approximately 85 to 95 percent by weight of the wholly aromatic polyester and approximately 5 to 15 percent by weight of a polyalkylene terephthalate. Accordingly, the wholly aromatic polyester which is capable of forming an anisotropic melt phase serves as the continuous phase in the resulting blend.

Abstract: A process is provided for forming a novel polymer blend which exhibits an anisotropic melt phase wherein there is chemical interaction between previously formed polymeric blend components to yield a product which is capable of forming shaped articles having highly satisfactory mechanical properties. The process comprises intimately mixing together approximately 50 to 75 percent by weight of polyalkylene terephthalate and 25 to 50 percent by weight of a melt processable polyester which is capable of forming an anisotropic melt phase. A post-polymerization subsequently is conducted in the solid phase in a non-oxidizing atmosphere at a temperature within the range of approximately 250.degree. to 300.degree. C. for a period of time in the range approximately 8 to 72 hours to yield the desired chemical interaction between the previously formed polymeric blend components.
