N2 - Several epoxy oligomers, A-X-A series, in which the A represents epoxy group, and the X is molecular block between epoxy groups, were synthesized or selected to compatibilize the blends of polysulfone (PSF)/a semiaromatic Thermotropic Liquid Crystalline Polymer (TLCPA1) and the blends of polycarbonate (PC)/TLCPA1. The results of Differential Scanning Calorimetry (DSC). Scanning Electronic Microscopy (SEM), and mechanical properties measurement of these compatibilized blends showed that the compatibilizing effects of these epoxy oligomers relied on the structure and the spacing block length of X. Among them, one new epoxy oligomer, which was made from allyl bisphenol-A and E-44 (a bisphenol-A epoxy resin, epoxy equivalent: 230), has been demonstrated to be a highly efficient compatibilizer for PSF/TLCPA1 blends. Adding 2% of this compatibilizer to PSF/TLCPA1 blend led to a 6.7% and 9.7% increase of bending strength and tensile strength, respectively.
