摘要
The invention relates to the use of dicyanamide-containing ionic liquids which decrease the cure temperature of cyanate esters to form unique thermoset polymers having a triazine network. These thermoset polymers having the triazine network have an ionic character allowing for use in varied applications. The thermoset polymers described herein are useful in high temperature performance composites, and their high Tg makes them useful as a substitute for epoxies in the microelectronics industry. The thermoset polymers have good fracture toughness, excellent substrate adhesion, low shrinkage, and low moisture uptake.
