The highest DP of 137 was obtained when diphenyl ether and tetrafluoro-m-phenylene were used as linkers L1 and L2, respectively (PP 5; Table 1). Chromophores such as fluorene, triphenyl amine and quinoxaline could be directly incorporated into the polymer backbone, providing blue-emitting ...
The bPPO (1 g) was dissolved in 20 mL NMP. To this dispersion, 1.4 g DABCO was then added and stirred at 70 °C for 24 h. The reaction content was precipitated in diethyl ethyl (100 mL) and washed with diethyl ether and ethyl acetate. The obtained product was then dr...
Various methods have been developed to enhance the adhesive properties between polyphenylene ether resin compositions and foamed polyurethane. For example, U.S. Pat. No. 5,370,813 describes the addition of various primary and secondary amines to compositions of polyphenylene ether resin and alkenyl ...
