A novel dicyanate, 4,4′-biscyanato-2,2′-trifluoromethylbiphenyl (TFMBDCy), and its thermoset were prepared, and their properties were systematically compared to those of polycyanurates derived from bisphenol A dicyanate (BADCy). The TFMBDCy network exhibited a much higher glass transition temperature, enhanced toughness, reduced water uptake, and improved dielectric properties compared to the BADCy-derived polycyanurate. These improvements resulted from the fluorinated, rigid but non-coplanar architecture of TFMBDCy.

衍生自4,4'-biscyanato-2,2'-三氟甲基联苯的高性能聚氰尿酸酯网络

制备了一种新型的双氰酸酯4,4'-biscyanato-2,2'-三氟甲基联苯（TFMBDCy），并对其热固性进行了系统地比较，并将其性能与衍生自双酚A双氰酸酯（BADCy）的多氰脲酸酯进行了比较。与BADCy衍生的聚氰尿酸酯相比，TFMBDCy网络表现出更高的玻璃化转变温度，更高的韧性，更低的吸水率和更高的介电性能。这些改进来自TFMBDCy的氟化，刚性但非共面结构。
