Cyanate ester (CE resins), also known as polycyanurate networks, are thermoset polymers that offer an outstanding combination of physical properties that have made them highly desirable for applications ranging from printed circuit boards and radomes to magnet casings for thermonuclear fusion reactors and aerospace components. Since many of the desired properties of CE resins are shared with fluorinated polymers, a logical approach to further optimize polycyanurate networks is to impart fluorinated moieties to the polymer backbone. In previous accounts, we introduced the first of a new class of fluorinated cyanate ester resins that exhibited extremely low moisture uptake at full cure which was among the lowest values measured for any polycyanurate network. Herein we present the synthesis and characterization of a new perfluorocyclic-functionalized polycyanurate derived from bisphenol A and perfluorocyclopentene.
