中文摘要	phase behavior, thermal, theological and mechanical properties plus morphology have been studied for a binary polymer blend. the blend is phenolphthalein polyethersulfone (pes-c) with a thermotropic liquid crystalline polymer (lcp), a condensation copolymer of p-hydroxybenzoic acid with ethylene terephthalate (phb-pet). it was found that these two polymers form optically isotropic and homogeneous blends by means of a solvent casting method. the homogeneous blends undergo phase separation during heat treatment. however, melt mixed pes-c/phb-pet blends were heterogeneous based upon dsc and dma analysis and sem examination. addition of lcp in pes-c resulted in a marked reduction of melt viscosity and thus improved processability. compared to pure pes-c, the charpy impact strength of the blend containing 2.5% lcp increased 2.5 times. synergistic effects were also observed for the mechanical properties of blends containing < 10% lcp. particulates, ribbons, and fibrils were found to be the typical morphological units of phb-pet in the pes-c matrix, which depended upon the concentration of lcp and the processing conditions.
