A combination of excellent mechanical and thermal properties with good flow and favorable price is very required for polymeric materials. Thermotropic liquid crystal polyester/polycarbonate (TLCP/PC) blends are well suited for the production of thin-walled electric/electronic parts with outstanding mechanical strength, heat resistance, excellent shape stability, and soldering resistance. However, melt-processible TLCP/PC blends are immiscible in the molecular level. In this study, we have investigated the influences of organometallic transesterification catalysts on the compatibilization of TLCP/PC blends. For the purpose, TLCP/PC blends different mixing ratios are melt-compounded in the presence of transesterification catalysts. The morphological features of the blends are characterized using SEM, FT-IR, and XRD. The crystallization kinetics, thermal transition, thermal stability, rheological and mechanical properties of the blends are investigated using DSC, TGA, rheometer, and DMA.
