Polarized photomicrog., SEM, wide-angle x-ray diffraction, IR spectrometry, and microhardness testing were used to evaluate the microstructure of injection-molded LCP 2000 polyester samples. The distributions of the various properties were affected by the development of morphol. structures and layer formation in the depth direction of the moldings. Molding conditions played an important role in the development of morphol. tones. The various techniques gave results in good agreement with a proposed morphol. model for the skin-core structure.
