Poly(2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylenevinylene) (MEH-PPV) and poly(2,3-diphenyl-5-octyl-p-phenylenevinylene) (DPO-PPV) are basically immiscible as verified by fluorescence spectroscopy and differential scanning calorimetry. This immiscibility results in insufficient energy transfer from DPO-PPV to MEH-PPV in photoluminescence. A vertically segregated structure with DPO-PPV green domains...
The glycolysis of poly (ethylene-terephthalate) with bisphenol-A at certain ratios of PET/BPA was carried out in an autoclave reactor at different temperatures for varying periods of time. Then the glycolyzed products were utilized together with bisphenol-A for the synthesis of polyarylates through interfacial polycondensation. The polyarylates obtained (referred to as b/g-polyarylates in this article)...
