Abstract
A method for rending melt processable a liquid crystal polymer otherwise not readily processable as a result of an interfering degradation temperature or an elevated viscosity. In the method the liquid crystal polymer is blended with a second, low molecular weight liquid crystal diester to form a miscible mesophase which is typified by a reduced viscosity and or at a lower temperature may be formed into a desired configuration. The low molecular weight liquid crystal may be then transesterified into the polyester to produce a long chain having desirable final liquid crystal polymer properties.
