Polymerization without volatile gases leads to high-quality resins. N-CYCAP (amiNe substituted CYClophane Addition Polyimide) is thermoset polyimide developed containing 4-amino{2.2}paracyclophane as end cap. Current improvements in synthesis of end cap include increasing yield to 60 percent overall and decreasing manufacturing time by simplifying synthetic procedure. Enables large-scale production and increases viability of cyclophane end caps for polymers for high-temperature applications. In comparison with neat resin moldings and composite matrix resins made of PMR-II-50, those made of N-CYCAP polymers found to be processable with lower void content and higher thermo-oxidative stability.
